RNA-Solv Reagent®RNA Isolation SolventWARNING: This reagent is toxic if swallowed and in contact with skin. Causes burns. After contact with skin, wash immediately with copious amounts of mild detergent and water. If you feel sick, seek medical advice at once and Quote UN2821.Product No:R6830-00 (5 ml)R6830-01 (100 ml)R6830-02 (200 ml)Storage Conditions:RNA-Solv is stable for at least 24 months®when stored at 2°C-8°C and yields reproducible results.IntroductionRNA-Solv® Reagent is a reagent system for the isolation of total RNA from cells and tissues. The reagent, a single-phase solution consisting of phenol and guanidine isothiocyanate, is modification of the single-step RNA isolation method developed by Chomczynski and Sacchi (1).The sample is homogenized and lysed in RNA-Solv® Reagent which maintains the integrity of the RNA, while disrupting and denaturing endogenous RNases and other cellular components. Extraction of the lysate with chloroform further denatures proteins and separates the mixture into an organic and an aqueous phase. RNA remains exclusively in the aqueous phase, and is subsequently recovered by isopropanol.This method is suitable for small quantities of tissue (<100 mg) and cells (<5 X10), and large quantities of tissue ( up to1 g) and cells 6(<10 ), of human, animal, plant, or bacterial origin. The simplicity 8of the RNA-Solv® Reagent method allows simultaneous processing of a large number of samples. The entire procedure can be completed in one hour. Total RNA prepared in this manner can be used for Northern blot analysis, dot blot hybridization, poly(A) + selection, in vitro translation, RNase protection assay, and molecular cloning. For use in amplification by thermal cycling, treatment of the isolated RNA with RNase-free DNase I is recommended when the two amplimers lie within a single exon.Supplied By User•Chloroform (no isoamyl alcohol added)•Isopropyl alcohol•80% Ethanol (in DEPC-treated water)•RNase-free water•Tabletop centrifuge capable of 12,000 x g at room temperatureGeneral Notes Regarding RNase ContaminationWhenever working with RNA :•Always wear disposable gloves and change gloves frequently.•Use sterile, disposable plasticware and automatic pipettes reserved for RNA work to prevent cross-contamination with RNases.•In the presence of RNA-Solv® Reagent, RNA is protected from RNase contamination. Downstream sample handling requires that nondisposable glassware or plasticware be RNase-free.•Use only DECP-treated buffers. Add DEPC to a final concentration of 0.1%, incubate at 37C for 2 hours, andoautoclave at 121C. Do not add DEPC to Tris buffers. Suchobuffers must be prepared by using DECP-water.PrecautionUse only disposable polypropylene tubes for small samples and glass Corex tubes for larger samples. All tubes must be able to withstand 12,000 x g . Polystyrene tubes may crack with chloroform Before StartingA.Small Samples :To isolate RNA from very small samples (<106 cells or <10 mg tissue) perform homogenization (or lysis) of samples in 0.8 mL of RNA-Solv®, and add 1 mg RNase-free glycogen or yeast tRNA as carrier. This will improve yields obtained with precipitation.B.Difficult Animal Samples: Specimens containing large amounts of proteins, fat, polysaccharides or extracellular material such as muscles, fat tissue, and sperm, will require the following modification. After lysis/homogenization in RNA-Solv® Reagent, centrifuge at 12,000 x g for 10 minutes at room temperature to remove insoluble debris. Often a precipitate forms at the bottom of the tube, but with fatty tissue, a lipid layer will also form above the aqueous phase. The supernatant will contain the RNA and must be carefully transferred to a fresh 1.5 ml microfuge tube before proceeding.C. Interruption the procedure:Following lysis in RNA-Solv®Reagent and before addition of chloroform, samples can be stored at -70C for up to 3 months. In addition, once the RNA is oprecipitated in isopropanol, the pellet may be stored at -20C or -o70C for up to 1 year.oRNA-Solv Protocol for Total RNA Isolation®CAUTION: When working with RNA-Solv® Reagent use gloves and eye protection (safety goggles) and avoid contact with skin or clothing. Work in a chemical fume hood to avoid inhaling vapor. Unless otherwise noted, all steps are to be carried out at room temperature (20C-25C).o o1. Homogenization and lysis of samples: follow either method belowa) Tissue SamplesHomogenize tissue samples in 1 mL of RNA-Solv® Reagent per 50-100 mg of tissue using an appropriate mechanical homogenizer. Alternatively one can pulverize tissue in liquid nitrogen with mortar and pestle and transfer the powder to a clean 1.5 ml microcentrifuge tube. If ceramic mortar and pestle are not available, homogenize the sample in the microfuge tube using a disposable microtube pestle (Eppendorf, Cat No. 0030 120.973; VWR, Cat No. KT 749520-0000). The sample volume should not exceed 10% of the volume of RNA-Solv® Reagent used.b) Cells Grown in SuspensionPellet cells by centrifugation. Lyse cells in RNA-Solv® Reagent by repetitive pipetting. Use 1 mL of the reagent per 5-10 x 10of6 animal, plant or yeast cells, or per 1 x 10 bacterial cells. Washing8cells before addition of RNA-Solv® Reagent should be avoided as this increases the possibility of mRNA degradation and RNase contamination. For plant, fungal, and yeast cells mechanical or enzymatic homogenization may be required. Also, for plant, fungal, and yeast cells, we recommend the use of the E.Z.N.A.® Plant (R6627),Fungal (R6640), and Yeast (R6670) RNA Kits from Omega Bio-tek.c) Cells Grown in MonolayerLyse cells directly in a culture dish by adding 1 mL of RNA-Solv®Reagent to a 3.5 cm diameter dish, and passing the cell lysate several times through a blue pipette tip. The amount of RNA-Solv®Reagent added is based on the area of the culture dish (~1 mL per 10 cm ). An insufficient amount of RNA-Solv® Reagent may result2in contamination of the isolated RNA with DNA. Always use more RNA-Solv® Reagent if in the lysate is too viscous to aspirate with a pipette.2. Add 0.2 mL of chloroform per 1 mL of RNA-Solv® Reagent. Cap sample tubes securely and vortex vigorously for 15 seconds. Incubate on ice for 10 minutes. This step is critical - do not change it.3. Centrifuge the samples at no more than 12,000 x g for 15 minutes 4E C.The mixture separates into a lower phenol-chloroform phase, an interphase, and an upper aqueous phase. RNA remains entirely in the aqueous phase.4. Precipitation of RNA.Transfer no more than 80% of the aqueous phase to a fresh tube, and discard the lower organic phase. Precipitate the RNA from the aqueous phase by adding 500ìl of isopropyl alcohol per 1 mL of RNA-Solv® Reagent used for the initial homogenization. Incubate samples at room temperature 10 minutes and centrifuge at no more than 12,000 x g for 10 minutes also at room temperature.Carbohydrate-rich samples: Plant samples of high polysaccharide content or animal tissues rich in glycosaminoglycans (proteoglycans) require the following modified precipitation method for obtaining pure RNA. Prepare Buffer A ( 1.2 M sodium chloride, 800 mM sodium citrate). Following step 3, add to the aqueous phase 0.3 ml isopropanol followed by 0.3 ml Buffer A per 1 ml RNA Solv ® Reagent used in step 1. Vortex to mix and centrifuge at no more than 12,000 x g for 10 minutes at room temperature. This high salt precipitation will reduce co-purification of complex carbohydrates.5. Wash RNA pellet. Discard the supernatant and wash the RNA pellet once with 1 ml 80% ethanol. Mix the sample by vortexing and centrifuge at no more than 7,500 x g for 5 minutes at room temperature.6.Reconstitute RNA. Carefully aspirate and discard the ethanol and briefly AIR DRY the RNA pellet for 2-5 minutes at room temperature. Do not use centrifugal devices equipped with a vacuum source as over-drying will lead to difficulty in re-dissolving RNA in water. Dissolve RNA in RNase-free water - a 5 minute incubation at 60 °C may be required. RNA can also be reconstituted in 100% formamide (deionized) and stored at -70°C.RNA is now suitable for RNase protection, northern analysis and reverse transcriptase reactions. For isolation of poly(A)+ RNA an additional ethanol precipitation is required. Add 1/8 X volume of RNase-free 3M NaAc, pH 6.0 followed by 2.5 X volume absolute ethanol. Vortex to mix and incubate at room temperature for 5 minutes. Centrifuge at 12,000 x g for 10 min at room temperature and discard the supernatant. Wash the pellet as before and reconstitute in DECP-treated water.Determination of Yield and QualityUV spectrophotometric analysis of the purified RNA is required for obtaining yield. To do so, dilute the RNA in an appropriate volume of TE buffer, pH 8.0 (not water; RNA yields low Abs ratio values if dissolved in acidic buffers) and measure absorbance at 260 nm and at 280 nm. RNA Conc = 40 ìg/ml X Dilution factor X Abs 260 nmTypical Abs 260 nm/ 280 nm ratios of 1.7-1.9 are obtained with the protocol. Yields vary depending of type and amount of starting material, and on condition of storage prior to processing. For assessing the quality of RNA, we recommend you perform denaturing agarose gel electrophoresis to confirm the integrity of purified material. Invariably, the full spectrum of RNAs, including 4S and 5S species are purified with RNA-Solv® Reagent.Expected Yields per 1 mg tissue or 10 cells:6Liver and spleen, 5-10 ìgKidney, 2-5 ìgBrain, 1-2ìgEndothelial cells, 7-12 ìgFibroblasts, 6-8ìgTroubleshooting•Low RNA Yields: Incomplete lysis of samples in RNA Solv Reagent. RNA pellet not completelt dissolved in DEPC-water.pH of diluent used for spectrophotometric analysis is too low.•Degraded RNA: Tissues were not immediately processed or frozen.

The key to this systemis that it uses the reversible binding properties of the HiBind Matrix in combinationwith the speed of mini-column spin technology thereby permitting single or multiple simultaneous processing of samples. There is no need for phenol/chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation, or precipitation with isopropanol or LiCl are eliminated. RNA purified using the E.Z.N.A.® RNA Purification System is ready for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.The E.Z.N.A.® Total RNA Kit I can purify up to 100 μg of total RNA from cultured eukaryotic cells or tissue. Normally, 1 x 106 - 1 x 107 eukaryotic cells, or 5-30 mg of tissue, can be processed in a single experiment. Fresh, frozen or RNALater® stabilized tissues can be used. Lysis of cells or tissue occurs under denaturing conditions which inactivate RNases. After the homogenization process, samples are applied to the HiBind RNA spin column to which total RNA binds. Cellular debris and other contaminants are effectively washed away after a few quick wash steps. High quality RNA is finally eluted in DEPC treated water. Total RNA greater than 200 nt is isolated using this kit.For isolating total RNA below 200 nt use the miRNA isolation Kit (R7034). For isolating total RNA from gram positive bacteria, the recommended kit is the Bacterial RNAKit(R6950).While this kit may be used for the isolation of RNA from whole blood, we recommend that you use the E.Z.N.A.® Blood RNA Kit (Product # R6814) as it is specifically designed for effective hemolysis and hemoglobin removal, thereby giving higher RNA yields. Binding CapacityEach HiBind RNA Mini column can bind approximately 100μg of RNA. Using greater than 30 mg of tissue or 1 x 107 cells is not recommended.23Kit ContentsStorage and StabilityAll E.Z.N.A.® Total RNA Kit components are guaranteed for at least 12 months from the date of purchase when stored at room temperature. During shipment, crystals or precipitation may form in the TRK Lysis Buffer. Dissolve by warming buffer to 37°C.4Preparing Reagents• Dilute RNA Wash Buffer II with absolute ethanol (96-100%) as follows:• Store diluted RNA Wash Buffer ll at room temperature.• Please remember to always wear gloves whenever working with RNA. This will minimize RNase contamination. Use only clean RNase-free disposable plastic pipette tips when us-ing the supplied reagents.• Under cool ambient conditions, crystals may form in TRK Lysis Buffer. This is normal; warm at 37°C to dissolve.• Optional: As a preparation step add 20µl of 2-mercaptoethanol (β-mercaptoethanol) per 1 ml of TRK Lysis Buffer in order to achieve a working solution. This mixture can be stored for 1 week at room temperature.5Guideline for Vacuum ManifoldThe following is required for use with the Vacuum Protocol:A) Vacuum Manifold (We recommend Omega Bio-tek’s VAC-08)Other Compatible Vacuum Manifolds: Qiagen QIAvac24, Sigma AldrichVM20, Promega Vacman®, or manifold with standard Luer connectorB) Vacuum FlaskC) Vacuum TubingD) Vacuum Source (review tables below for pressure settings)B) Vacuum Flask D) Vacuum SourceIllustrated Vacuum Setup:67Quantification of RNAStorage of RNAPurified RNA can be stored at -70°C (RNase-free water). Under such conditions, RNA prepared with the E.Z.N.A.® Total RNA Kit l is stable for more than a year.Quantification of RNATo determine the concentration and purity of RNA, one should measure theabsorbance at 260 nm and 280 nm in a spectrophotometer. 1 O.D. unit measured at 260 nm corresponds to 40μg of RNA per ml. DEPC treated water is slightly acidic and can dramatically lower absorbance values. We suggest that you dilute thesample in a buffered solution (TE) for spectrophotometric analysis. The A 260/A 280 ratio of pure nucleic acids is 2.0, while for pure protein is approximately 0.6. Therefore, a ratio of 1.8-2.0 corresponds to 90-100% pure nucleic acid. [Phenol has a maximum absorbance at 275 nm and can interfere with absorbance readings of DNA or RNA.However, the E.Z.N.A.® Total RNA Kit eliminates the use of phenol and avoids this problem.]RNA QualityIt is highly recommended that RNA Quality be determined prior to all analysis. The quality of RNA can be best assessed by denaturing agarose gel electrophoresis and ethidium bromide staining. Two sharp bands should appear on the gel. These are the 28S and the 18S (23S and 16S for bacteria) ribosomal RNA bands. If these band appears as a smear towards lower molecular weight sized RNAs, the it is likely that RNA has undergone major degradation during preparation, handling, or storage.Although RNA molecules less than 200 bases in length do not efficiently bind to the HiBind matrix, a third RNA band, the tRNA band, may be visible when a large number of cells are used.Expected YieldsFor animal cell yields, see page 9.For animal tissue yields, see page 14.Disruption and Homogenization of SamplesEfficient sample disruption and homogenization is essential for successful Total RNA isolation. Complete cell wall and plasma membrane disruption is very important for the release of all of the RNA contained in the sample. The purpose of homogenization is to reduce the viscosity of the cell lysates produced by cell disruption. Homogenization shears genomic DNA and other high molecular weight cell components thereby creating a homogenous lysate. Incomplete homogenization will cause RNA binding to clog thus preventing efficient RNA binding result in low or no yield.Mortar and Pestle: Sample DisruptionSample disruption using a mortar and pestle followed the chosen of homogenization method:Wear gloves, and take great care when working with liquid nitrogen.1. Excise tissue and promptly freeze in a small volume of liquid nitrogen.2. Grind tissue with a ceramic mortar and pestle under approximately 10 ml of liquidnitrogen. Pour the suspension into a pre-cooled 15ml polypropylene tube. The tube must be pre-cooled in liquid nitrogen or the suspension will boil vigorously possibly causing tissue loss.3. Allow the liquid nitrogen to completely evaporate and add TRK lysis buffer. Homogenization:A) Homogenizer Spin column (Product # HCR 003)Load the lysate into a homogenizer spin column pre-inserted into a 2ml collection tube. Spin for two minutes at maximum speed in a micro centrifuge in order tocollect homogenized lysate.B) Syringe and NeedleShear High molecular-weight DNA by passing the lysate through a narrowneedle (19-21 gauge) 5-10 times.Rotor-Stator Homogenizer: Sample Disruption and HomogenizationUsing a rotor-stator homogenizer for sample disruption and homogenization can simultaneously disrupt and homogenize most samples. The process usually takes less than a minute depending on sample type. Many Rotor-stator homogenizers operate with differently sized probes or generators that allow sample processing in 50ml tubes. Bead Milling: Sample Disruption and HomogenizationBy using bead milling, cells and tissue can be disrupted and homogenized byrapid agitation in the presence of glass beads and a lysis buffer. The optimal amount of glass beads to use for RNA isolation are 0.5mm for yeast/unicellular cells and 4-8mm for animal tissue samples.8Total RNA Kit I - Animal Cell ProtocolE.Z.N.A.® Total RNA Kit I Animal Cell ProtocolAll centrifugation steps used are preformed at room temperature.General Protocol Equipment:• Absolute(~96-100%) Ethanol• Sterile RNase-free pipet tips and 1.5ml centrifuge tubes• Optional: 14.3M β-mercaptoethanol (β-ME, 2-mercaptoethanol)• Microcentrifuge capable of at least 14,000 x g• 70% ethanol in Sterile DEPC-treated Water.• Disposable glovesSample Disruption and Homogenization Equipment:• Omega Homogenizer Columns (HCR003)• Needle and Syringe• Mortar and pestle• Glass Beads• Rotor-stator HomogenizerThings to do before starting:• Optional: As a preparation ste p add 20μl of 2-mercaptoethanol (β-mercaptoethanol) per 1 ml of TRK Lysis Buffer in order to achieve a working solution. This mixture can be stored for 1 week at room temperature.1. Determine the proper amount of starting material: It is critical to use the correctnumber of starting cells in order to obtain optimal yield and purity with the HiBind RNA column. The maximum number of cells that can be processed on a HiBindRNA column is dependent on the specific RNA contents and type of cell line. Themaximum binding capacity of the HiBind RNA column is 100µg. The maximumnumber of cells that TRK Lysis Buffer can use in the Total RNA Protocol is 1 x 107. Use the following table as a guideline to select the correct starting material.Expected Yield9102.Harvest cells by choosing one of the following methods (A or B).(do not use more than 1 x 107 cells)A) For cells grown in suspension: determine the number of cells. Pellet theappropriate number of cells by centrifuging at 500 x g for 5 minutes. Aspirate the supernatant and continue with step 3 of this protocol. OrB) For cells grown in a monolayer: These cells can either be lysed directly in the cell culture dish or trypsinized and collected as a cell pellet prior to lysis. Cells grown in cell-culture flasks should always be trypsinized.i. For direct cell lysis:Determine cell number, and aspirate the cell-culture medium completely. Immediately proceed to step 3.NOTE: Not removing cell-culture medium completely will inhibit lysis anddilute the lysate. This will affect the conditions for binding of RNA to the HiBind RNA column, and may reduce RNA yield.ii. To trypsinize and collect cells:Determine cell number. Aspirate the medium and wash cells with PBS. Aspirate the PBS, add 0.1-.25% trypsin into PBS. Add medium (containing serum to inactivate the tryspin), after the cells detach from the dish or flask. Transfer cells to an RNase-free glass or polypropylene centrifuge tube (not supplied), and centrifuge at 500 x g for 5 minutes. Aspirate the supernatant completely, and proceed to step 3.Note : Not removing cell-culture medium completely will inhibit lysis and dilute the lysate. This will affect the conditions for binding of RNA to the HiBind RNA column, and may reduce RNA yield.3.Disrupt cells (do not use more than 1 x 107 cells) with TRK Lysis Buffer.For pelleted cells, loosen the cell pellet thoroughly by flicking the tube, and adding the appropriate amount of TRK Lysis Buffer based on the table below. Mix throughlyby vortexing or pipetting.Total RNA Kit I - Animal Cell ProtocolFor direct lysis of cells grown in a monolayer, add the appropriate amount of TRK Lysis Buffer directly to the cell culture dish based on the table below. Collect the cell lysate with a rubber policemen and transfer the cell lysate into a 1.5 ml centrifuge tube. Mix throughly by vortexing or pipetting. Make sure there is no visible cell clumps in the sample.4. Homogenize and disrupt the tissue accordingly to one of the following steps:1. Rotor-Stator Homogenizer: Homogenize cells with a rotor-stator homogenizer oruntil the sample is uniformly homogenized. See Page 8 for details.2. Syringe and Needle: S hear high molecular-weight DNA by passing the lysate through a narrow needle (19-21 gauge) 5-10 times.3. Omega Homogenizer Column (HCR003): Load the lysate into a homogenizer spin column pre-inserted into a 2ml collection tube. Spin for two minutes at maximum speed in a micro centrifuge in order to collect homogenized lysate. Note : Incomplete homogenization of the sample will cause clogging colum thus resulting lower yields or no yield. It is recommended to homogenize the tissue sample with rotor-stator homogenizers since it normally produces better yields. 5.Add an equal volume (350µl or 700µl) of 70% ethanol to the lysate and mixthoroughly by pipetting up and down 3-5 times. Do not centrifuge. If any sample has lost its volume during homogenization, adjust the volume of ethanol accordingly. Note: During RNA purification from certain cell lines, a precipitate may form after the addition of ethanol. This does not affect the procedure. 6.Apply the sample ( including any precipitate that may have formed) to a HiBind RNA column inserted into a 2ml collection tube (supplied). Centrifuge at 10,000 x g for 60 seconds at room temperature. Discard flow-through and reuse the collection tube in the next step.Note: The maximum capacity of the HiBind RNA spin column is 700µl. Largervolumes can be loaded on to the column successively in the same HiBind RNA spin column. Discard flow-through after each centrifugation.Optional: This is the starting point if performing the optional on-column DNase Idigestion . Follow protocol as outlined on page 18, after completing this step.Total RNA Kit I - Animal Cell ProtocolTotal RNA Kit I - Animal Cell Protocol7.

Asecond elution may be necessary if the expected yield of RNA is > 30 µg.E.Z.N.A.® Total RNA Kit I DNase Digestion ProtocolFor most downstream applications it is not necessary to do DNase digestion due to HiBind RNA resin and spin column technology removing nearly all DNA without the need for DNase Treatment. However, certain sensitive RNA applications might require further removal of DNA. In such case, we recommend that you please follow the outlined steps below using product E1091.Note: After completing steps 1-5 of either of the centrifugation protocols or steps 1-2 of the vacuum protocol (making sure that all of the sample has completely passed through the HiBind RNA column), proceed with the following steps.All centrifugation steps used are preformed at room temperature.User Supplied Material:• RNase Free DNase Set (E1091)1. For each HiBind RNA column, prepare the DNase I stock solution as follows: ArrayNote:• DNase I is very sensitive to physical denaturation, therefore do not vortex this DNase I mixture. Please mix by GENTLY inverting the tube. Remember to freshlyprepare DNase I stock solution right before RNA isolation.• E.Z.N.A.® DNase I Digestion Buffer is supplied with Omega Bio-Tek, Inc.’s RNase-Free DNase Set (product no. E1091). Standard DNase Buffers are not compatiblewith on-membrane DNase digestion. The use of other buffers may affect thebinding of RNA to the HiBind matrix, reducing RNA yields, and purity.2.

2．匀浆化裂解产物“裂解和匀浆化样品”－第四页有更详细的说明，如果细胞≤1*105，漩涡振荡1min。

样品匀浆化不完全会显著的减少RNA的产量并容易造成柱子堵塞。

a)用匀浆器（rotor-stator ）30 s，使样品匀浆化，而后进行第3步。

b)使裂解产物通过钝的针头的注射器（0.9mm直径20-gauge），使之匀浆化。

注射器要除RNase。

进行第3步。

c)将裂解物转移入omega homogenizer spin column,10000g离心1分钟。

将流出液移入新的tube中，进行第3步。

组织的步骤：1．TRK裂解缓冲液在离心管中裂解细胞，使用前每1ml TRK裂解缓冲液加入20ul的β－巯基乙醇。

350ulTRK裂解液最多能有效裂解20mg组织（-3mm3）。

对20mg以上组织用600ul的TRK裂解液。

然而，不要超过30mg组织，这是推荐的最大量。

OMEGA小提试剂盒提取质粒步骤(中文翻译版)

质粒提取（小提，mini kit）1、将携带目的质粒的大肠杆菌接种于含10~15ul基础培养基/氨苄西林培养介质的50ml培养瓶中。

2、室温下5000×g离心10min。

3、弃去上清，剩余沉淀物中加入500ul的SolutionⅠ/RNase A，彻底混匀。

4、将混悬液移至新的2ml离心管中，加入500ul SolutionⅡ，轻柔彻底混匀，可得清亮的细菌裂解物，室温下孵育2min（混匀时用力过大，可破碎出染色体DNA，使目的质粒纯度下降）。

5、向4中液体加入250ul预冷的Buffer N3，轻柔、彻底混匀，直到出现白色絮状沉淀，4℃≥12000×g离心10min（可室温，最好4℃）（Buffer应彻底混匀，若混合物粘稠呈棕色或呈球状，应多混匀几次以中和溶液，溶液的彻底中和对于获得好的产出是必要的）。

6、小心吸取并将上清液转移进新的1.5ml离心管1：0.1的比例向上清液中加入ETR Solution 混匀溶液并于冰上孵育10min，孵育过程中颠倒几次以混匀（加入ETR Solution后，细菌裂解物将出现浑浊，但冰上孵育后将变澄清）（勿用2ml离心管收集上清，因为2ml离心管中有太多液体时，ETR Solution将悬浮于溶液中）。

7、将6中液体于42℃孵育5min，溶液将再次变浑。

室温下12000×g离心3min，ETR Solution将于离心管底部形成蓝色层。

8、将上层水相转移入新的2ml离心管中，按1：0.5的比例加入无水乙醇（室温，96~100％），轻柔混匀，室温下孵育1~2min。

9、将8中的溶液取700ul到柱子中，组装收集管，室温下1000×g离心1min，弃去收集管中通过柱子的液体，柱子和收集管重复利用。

10、重复9中步骤，直到收集的细菌裂解物全部用完。

11、将500ul Buffer HB加入柱子中，室温下10000×g离心1min，弃去收集管中废液（目的：将残存的蛋白污染物除去，是获得高质量DNA所必需的）。
