pUC18+和+pUC19质粒图谱

pUC18 和pUC19质粒图谱pUC18 和pUC19 大小只有2686bp ,是最常用的质粒载体,其结构组成紧凑,几乎不含多余的DNA 片段,GenBank注册号为L08752(pUC18)和X02514(pUC19)。

由pBR322 改造而来,其中lacZ(MSC)来自M13mp18/19 图3-4 是其质粒图谱。

这两个质粒的结构几乎是完全一样的,只是多克隆位点的排列方向相反。

这些质粒缺乏控制拷贝数的rop基因,因此其拷贝数达500-700 。

pUC 系列载体含有一段lacZ蛋白氨基末端的部分编码序列,在特定的受体细胞中可表现α-互补作用。

因此在多克隆位点中插入了外源片段后,可通过α-互补作用形成的蓝色和白色菌落筛选重组质粒。

Selecttransformants on LB plates containing 50 to 100 µg/ml ampicillin.3.Analyze your transformants for the presence of insert by restriction digestion.4.Select a transformant with the correct restriction pattern and use sequencing toconfirm that your gene is cloned in the proper orientation.5.Transfect your construct into the mammalian cell line of interest using your ownmethod of choice. Generate a stable cell line, if desired.6.Test for expression of your recombinant gene by western blot analysis or functionalassay.1Cloning into pcDNA3.1Introduction Diagrams are provided on pages 3-4 to help you design a cloning strategy for ligating your gene of interest into pcDNA3.1. General considerations for cloning and transformation arelisted below.General Molecular Biology Techniques For help with DNA ligations, E. coli transformations, restriction enzyme analysis, purification of single-stranded DNA, DNA sequencing, and DNA biochemistry, please refer to Molecular Cloning: A Laboratory Manual (Sambrook et al., 1989) or Current Protocols in Molecular Biology (Ausubel et al., 1994).E. coli Strain Many E. coli strains are suitable for the propagation of this vector including TOP10F´,DH5α™-T1R, and TOP10. We recommend that you propagate vectors containing inserts inE. coli strains that are recombination deficient (rec A) and endonuclease A-deficient(end A).For your convenience, TOP10F´ is available as chemically competent or electrocompetentcells from Invitrogen.Item Quantity Catalog no.One Shot® TOP10F´ (chemically competent cells)21 x 50 µl C3030-03Electrocomp™ TOP10F´ 5 x 80 µl C665-55Ultracomp™ TOP10F´ (chemically competent cells) 5 x 300 µl C665-03Transformation Method You may use any method of your choice for transformation. Chemical transformation is the most convenient for most researchers. Electroporation is the most efficient and the method of choice for large plasmids.Maintenance of pcDNA3.1To propagate and maintain pcDNA3.1, we recommend resuspending the vector in 20 µl sterile water to make a 1 µg/µl stock solution. Store the stock solution at -20°C.Use this stock solution to transform a rec A, end A E. coli strain like TOP10F´, DH5α™-T1R, TOP10, or equivalent. Select transformants on LB plates containing 50 to100 µg/ml ampicillin. Be sure to prepare a glycerol stock of your plasmid-containing E. coli strain for long-term storage (see page 5).Cloning Considerations pcDNA3.1(+) and pcDNA3.1(-) are nonfusion vectors. Your insert must contain a Kozak translation initiation sequence and an ATG start codon for proper initiation of translation (Kozak, 1987; Kozak, 1991; Kozak, 1990). An example of a Kozak consensus sequence is provided below. Please note that other sequences are possible (see references above), but the G or A at position -3 and the G at position +4 are the most critical for function (shown in bold). The ATG initiation codon is shown underlined.(G/A)NNATG GYour insert must also contain a stop codon for proper termination of your gene. Please note that the Xba I site contains an internal stop codon (TCTAGA).continued on next page23Multiple Cloning Site of pcDNA3.1(+)Below is the multiple cloning site for pcDNA3.1(+). Restriction sites are labeled to indicate the cleavage site. The Xba I site contains an internal stop codon (TCTAGA).

Select 10-20 clones and analyze for the presence and orientation of your insert.We recommend that you sequence your construct with the T7 Promoter and BGH Reverseprimers (Catalog nos. N560-02 and N575-02, respectively) to confirm that your gene is in thecorrect orientation for expression and contains an ATG and a stop codon. Please refer to thediagrams on pages 3-4 for the sequences and location of the priming sites. The primers areavailable separately from Invitrogen in 2 µg aliquots.Preparing aGlycerol StockOnce you have identified the correct clone, purify the colony and make a glycerol stock forlong-term storage. You should keep a DNA stock of your plasmid at -20°C.•Streak the original colony out on an LB plate containing 50 µg/ml ampicillin. Incubatethe plate at 37°C overnight.•Isolate a single colony and inoculate into 1-2 ml of LB containing 50 µg/ml ampicillin.•Grow the culture to mid-log phase (OD600 = 0.5-0.7).•Mix 0.85 ml of culture with 0.15 ml of sterile glycerol and transfer to a cryovial.•Store at -80°C.TransfectionIntroduction Once you have verified that your gene is cloned in the correct orientation and contains an initiation ATG and a stop codon, you are ready to transfect your cell line of choice. Werecommend that you include the positive control vector and a mock transfection (negativecontrol) to evaluate your results.Plasmid Preparation Plasmid DNA for transfection into eukaryotic cells must be clean and free from phenol and sodium chloride. Contaminants will kill the cells, and salt will interfere with lipids decreasing transfection efficiency. We recommend isolating plasmid DNA using the S.N.A.P.™ MiniPrep Kit (10-15 µg DNA, Catalog no. K1900-01), the S.N.A.P. ™MidiPrep Kit (10-200 µg DNA, Catalog no. K1910-01), or CsCl gradient centrifugation.Methods of Transfection For established cell lines (e.g. HeLa), please consult original references or the supplier of your cell line for the optimal method of transfection. We recommend that you follow exactly the protocol for your cell line. Pay particular attention to medium requirements, when to pass the cells, and at what dilution to split the cells. Further information is provided in Current Protocols in Molecular Biology (Ausubel et al., 1994).Methods for transfection include calcium phosphate (Chen and Okayama, 1987; Wigler et al., 1977), lipid-mediated (Felgner et al., 1989; Felgner and Ringold, 1989) and electroporation (Chu et al., 1987; Shigekawa and Dower, 1988). Invitrogen offers the Calcium Phosphate Transfection Kit (Catalog no. K2780-01) and a large selection of reagents for transfection. For more information, please refer to our World Wide Web site () or call Technical Service (see page 13).Positive Control pcDNA3.1/CAT is provided as a positive control vector for mammalian transfection and expression (see page 12) and may be used to optimize transfection conditions for yourcell line. The gene encoding chloramphenicol acetyl transferase (CAT) is expressed inmammalian cells under the control of the CMV promoter. A successful transfection willresult in CAT expression that can be easily assayed (see below).Assay for CAT Protein You may assay for CAT expression by ELISA assay, western blot analysis, fluorometric assay, or radioactive assay (Ausubel et al., 1994; Neumann et al., 1987). If you wish to detect CAT protein using western blot analysis, you may use the Anti-CAT Antiserum (Catalog no. R902-25) available from Invitrogen. Other kits to assay for CAT protein using ELISA assay are available from Roche Molecular Biochemicals (Catalog no. 1 363 727) and Molecular Probes (Catalog no. F-2900).Creation of Stable Cell LinesIntroduction The pcDNA3.1(+) and pcDNA3.1(-) vectors contain the neomycin resistance gene forselection of stable cell lines using neomycin (Geneticin®). We recommend that you testthe sensitivity of your mammalian host cell to Geneticin® as natural resistance variesamong cell lines. General information and guidelines are provided in this section for yourconvenience.Geneticin®Selective Antibiotic Geneticin® Selective Antibiotic blocks protein synthesis in mammalian cells by interfering with ribosomal function. It is an aminoglycoside, similar in structure to neomycin, gentamycin, and kanamycin. Expression of the bacterial aminoglycoside phosphotransferase gene (APH), derived from Tn5, in mammalian cells results in detoxification of Geneticin®(Southern and Berg, 1982).Geneticin®Selection Guidelines Geneticin® Selective Antibiotic is available from Invitrogen (Catalog no. 10486-025). Use as follows:•Prepare Geneticin® in a buffered solution (e.g. 100 mM HEPES, pH 7.3).•Use 100 to 800 µg/ml of Geneticin® in complete medium.•Calculate concentration based on the amount of active drug (check the lot label).•Test varying concentrations of Geneticin® on your cell line to determine theconcentration that kills your cells (see below). Cells differ in their susceptibility to Geneticin®.Cells will divide once or twice in the presence of lethal doses of Geneticin®, so the effects of the drug take several days to become apparent. Complete selection can take up to 3 weeks of growth in selective media.Determination of Antibiotic Sensitivity To successfully generate a stable cell line expressing your gene of interest frompcDNA3.1, you need to determine the minimum concentration of Geneticin® required to kill your untransfected host cell line. We recommend that you test a range of concentrations to ensure that you determine the minimum concentration necessary for your host cell line.1.Plate or split a confluent plate so the cells will be approximately 25% confluent.Prepare a set of 7 plates. Allow cells to adhere overnight.2.The next day, substitute culture medium with medium containing varyingconcentrations of Geneticin® (0, 50, 100, 200, 400, 600, 800 µg/ml Geneticin®).3.Replenish the selective media every 3-4 days, and observe the percentage of survivingcells.4.Count the number of viable cells at regular intervals to determine the appropriateconcentration of Geneticin® that prevents growth within 2-3 weeks after addition of Geneticin®.continued on next pagePossible Sites for Linearization of pcDNA3.1(+)Prior to transfection, we recommend that you linearize the pcDNA3.1(+) vector. Linearizing pcDNA3.1(+) will decrease the likelihood of the vector integrating into the genome in a way that disrupts the gene of interest or other elements required for expression in mammalian cells. The table below lists unique restriction sites that may be used to linearize your construct prior to transfection. Other unique restriction sites are possible. Be sure that your insert does not contain the restriction enzyme site you wish to use to linearize your vector.Enzyme Restriction Site (bp)Location SupplierBgl II12Upstream of CMV promoter Invitrogen, Catalog no. 15213-028 Mfe I161Upstream of CMV promoter New England BiolabsBst1107 I3236End of SV40 polyA AGS*, Fermentas, Takara, RocheMol.

Remember to include a plate of untransfected cells as a negativecontrol and the pcDNA3.1/CAT plasmid as a positive control.2.24 hours after transfection, wash the cells and add fresh medium to the cells.3.48 hours after transfection, split the cells into fresh medium containing Geneticin® atthe pre-determined concentration required for your cell line. Split the cells such that they are no more than 25% confluent.4.Feed the cells with selective medium every 3-4 days until Geneticin®-resistant foci canbe identified.5.Pick and expand colonies in 96- or 48-well plates.AppendixpcDNA3.1 VectorsMap ofpcDNA3.1(+) and pcDNA3.1(-)The figure below summarizes the features of the pcDNA3.1(+) and pcDNA3.1(-) vectors.The complete sequences for pcDNA3.1(+) and pcDNA3.1(-) are available for down-loading from our World Wide Web site ( ) or from Technical Service (see page 13).

pGADT7
Vector Information
as a fusion to a hemagglutinin (HA) epitope tag. HA-tagged proteins can be identified with antibodies raised to this common epitope, eliminating the need to generate specific antibodies to new proteins. The T7 promoter is used for in vitro transcription and translation of the epitope tagged fusion protein and also provides a binding site for sequencing using the T7 Sequencing Primer. Note that the AD is not expressed during the in vitro transcription and translation reactions. The Nco I and Pst I sites may be used to shuttle inserts from pGADT7 into pGBKT7, the MATCHMAKER Two-Hybrid System 3 DNA-BD Vector. The MCS in pGADT7 is compatible with those in pMyc-CMV and pHA-CMV, CLONTECH's epitope tagged mammalian expression vector set (#K6003-1). As a result, the target gene can be shuttled into these vectors in order to confirm protein interactions in vivo.

如何阅读分析质粒图谱
载体主要有病毒和非病毒两大类,其中质粒DNA是一种非病毒转基因载体。

一、质粒的组成要素
复制起始位点Ori:即控制复制起始的位点。

原核生物DNA分子中只有一个复制起始点。

而真核生物DNA分子有多个复制起始位点。

抗生素抗性基因:可以便于加以检测,如Amp+,Kan+
多克隆位点MCS:克隆携带外源基因片段
P/E:启动子/增强子
Terms:终止信号
加poly(A)信号:可以起到稳定mRNA作用
二、如何阅读质粒图谱
第一步:首先看Ori的位置,了解质粒的类型(原核/真核/穿梭质粒)
第二步:再看筛选标记,如抗性,决定使用什么筛选标记。

(1)Ampr水解β-内酰胺环,解除氨苄的毒性。

(2)tetr可以阻止四环素进入细胞。

(3)camr生成氯霉素羟乙酰基衍生物,使之失去毒性。

(4)neor(kanr)氨基糖苷磷酸转移酶使G418(长那霉素衍生物)失活
(5)hygr使潮霉素β失活。

第三步:看多克隆位点(MCS)。

它具有多个限制酶的单一切点。

便于外源基因的插入。

如果在这些位点外有外源基因的插入,会导致某种标志基因的失活,而便于筛选。

决定能不能放目的基因以及如何放置目的基因。

第四步:再看外源DNA插入片段大小。

质粒一般只能容纳小于10Kb的外源DNA片段。

一般来说,外源DNA片段越长,越难插入,越不稳定,转化效率越低。

第五步:是否含有表达系统元件,即启动子-核糖体结合位点-克隆位点-转录终止信号。

这是用来区别克隆载体与表达载体。

克隆载体中加入一些与表达调控有关的元件即成为表达载体。

选用那种载体,还是要以实验目的为准绳。

启动子-核糖体结合位点-克隆位点-转录终止信号
启动子-促进DNA转录的DNA顺序,这个DNA区域常在基因或操纵子编码顺序的上游,是DNA分子上可以与RNApol特异性结合并使之开始转录的部位,但启动子本身不被转录。

λ
增强子/沉默子-为真核λ基因组(包括真核病毒基因组)中的一种具有增强邻近基因转录过程的调控顺序。

其作用与增强子所在的位置或方向无关。

即在所调控基因上游或下游均可发挥作用。

/沉默子-负增强子,负调控序列。

核糖体结合位点/起始密码/SD序列(Rbs/AGU/SDs):mRNA有核糖体的两个结合位点,对于原核而言是AUG(起始密码)和SD序列。

λ
转录终止顺序(终止子)/翻译终止密码子:结构基因的最后一个外显子中有一个AATAAA 的保守序列,此位点down-stream有一段GT或T富丰区,这2部分共同构成poly(A)加尾信号。

结构基因的最后一个外显子中有一个AA TAAA的保守序列,此位点down-stream 有一段GT或T富丰区,这2部分共同构成poly(A)加尾信号。
