Functions very well in the presence or absence of serum.For life science research only.Not for use in diagnostic procedures.Print2.How to Use this Product2.1Before You BeginRequired Amount of X-tremeGENE HP DNA Transfection ReagentTo optimize, first transfect a monolayer of cells that is 70 - 90% conflu-ent, using 1:1, 2:1, 3:1 and 4:1 ratios of microliter (?l) X-tremeGENE HP DNA Transfection Reagent to microgram (?g) DNA. A ratio of 3:1 of microliter (?l) X-tremeGENE HP DNA Transfection Reagent to micro-gram (?g) DNA has been shown to be optimal for many cell types.L Lower cell confluencies have also been tested successfully.The recommended starting concentration is a 3:1. For most cell types, these X-tremeGENE HP DNA Transfection Reagent to DNA ratios pro-vide excellent transfection efficiency.L Further optimization may increase transfection efficiency in your particular application. In addition to varying the ratio, other param-eters may also be evaluated, such as the amount of transfection complex added. For additional optimization guidelines, see Section 3, Troubleshooting and visit /doc/48879f4bad02de80d4d840ed.html .For best results, accurately determine the plasmid DNA concentra-tion using 260-nm absorption; estimates of DNA by measuring gel band density are not recommended. Determine DNA purity using a 260 nm/280 nm ratio (the optimal ratio is 1.8).Prepare the plasmid DNA solution using sterile TE (Tris/EDTA) buf-fer or sterile water at a concentration of 0.1 to 2.0 µg/µl. Use high quality DNA preparation kits to obtain endotoxin-free DNA.Cell Culture ConditionsMinimize intra- and inter-experimental variance in transfection effi-ciency using cells that are regularly passaged, proliferating well in a log-growth phase, and plated at a consistent density.For best results, accurately quantify cell concentration using a hematocytometer or automated system.Cells must be healthy and free of Mycoplasma.Cells should have a low passage number to achieve best results.Other Media AdditivesIn some cell types, antimicrobial agents (e.g., antibiotics and fungi-cides) commonly included in cell-culture media may adversely affect the transfection efficiency of X-tremeGENE HP DNA Transfection Reagent. If possible, exclude additives in initial experiments. Once high-efficiency conditions have been established, these components can be added back while monitoring transfection results. Cell growth and/or transfection efficiency may be affected by variations in serum quality and medium formulations.Verification of Vector FunctionOptimize transfection conditions using a known positive-control reporter gene construct before transfecting cells with a new vector construct:Determine transfection efficiency using a reporter gene assay, such as -Gal*, Luciferase*, or SEAP*.Sequence flanking vector insert regions to verify the integrity of your new construct.2.2Preparation of Cells for TransfectionAdherent Cells: Plate cells approximately 24 hours before transfec-tion making sure cells are at the optimal concentration in the appropri-ate cell culture vessel.Suspension Cells: Plate freshly passaged cells at optimal concentra-tion.2.3 Transfection ProcedureAllow X-tremeGENE HP DNA Transfection Reagent, DNA and diluent to equilibrate to +15 to +25°C. Briefly vortex theX-tremeGENE HP DNA Transfection Reagent vial.Dilute DNA with appropriate diluent (e.g., serum-free medium) to a final concentration of 1 µg plasmid DNA /100 µl medium (0.01 µg/µl). Mix gently.Place 100 µl of diluent, containing 1 µg DNA into each of four sterile tubes labeled 1:1, 2:1, 3:1, and 4:1.N Use a minimum of 100 µl of diluent. Lower volumes may significantly decrease transfection efficiency.L Use sterile tubes or tissue culture treated round-bottom, 96-well plates to produce the complex.Pipet the X-tremeGENE HP DNA Transfection Reagent (1, 2, 3, or 4 µl) directly into the medium containing the diluted DNA without coming into contact with the walls of the plastic tubes.Mix gently.N To avoid adversely affecting transfection efficiency, do not allow undiluted X-tremeGENE HP DNA Transfection Reagent to come into contact with plastic surfaces. Do notIncubate the transfection reagent:DNA complex for 15 min-utes at +15 to +25°C.L Some ratios and cell types may required longer incubation (up to 30 min). Determine this for your particular cell lineand the ratio used.Remove the culture vessel from the incubator. Removal of growth medium is not necessary. Add the transfection com-plex to the cells in a dropwise manner.L See Table 1 to determine component amounts corre-sponding to the surface area of the cell culture vesselused.Gently shake or swirl the wells or flasks to ensure even distri-bution over the entire plate surface. If available, use a rotatingplatform shaker for 30 seconds at low speed for mixing96-well plates.Once the transfection reagent: DNA complex has been addedto the cells, there is no need to replace with fresh medium (asmay be necessary with other transfection reagents)Following transfection, incubate cells for 18 – 72 hours before measuring protein expression. The duration of incubation will depend on many factors, including the transfected vector con-struct, the cell type being transfected, the cell medium, celldensity, and the type of protein being expressed. After theincubation period, measure protein expression using an assayappropriate for your system.Notes:L As with any experiment, include appropriate controls. Prepare cul-ture wells with cells that remain untransfected, cells with transfec-tion reagent alone, and cells with DNA alone.L For stable transfection experiments, the complex-containing medium should be left unchanged until the cells are passaged. At that time, include appropriate selection antibiotics (e.g., G 418 Solution or Hygromycin B).L To prepare transfection complexes for different-sized containers or parallel experiments, adjust component amounts correspond-ing to the surface area of the cell culture vessel used (see Table 1).L For ease-of-use when transfecting small volumes into 96-well plates containing 0.1 ml culture medium per well, prepare 100 µl of transfection complex, and then add 10 µl to each well (depend-ing on cell type).L The optimal ratio of transfection reagent to DNA, and the optimal total amount of complex, will depend on the cell line, cell density, day of assay, and gene expressed.L After performing the optimization experiment in which several dif-ferent ratios are tested, select a ratio in the middle of the plateau optimum for future experiments.Tab. 1: Guidelines for Preparing X-tremeGENE HP DNA Transfection Reagent: DNA Complex for Various Culture Vessel SizesCulture vessel Surface Areamedium (ml) Suggested amount of100 µl transfection complexto add toeach well (µl) DNA (µg)using 1:1or 4:1 RatioFinal amountof X-tremeGENE HP DNA Transfection Reagent (µl) using 1:1 Ratio Final amountof X-tremeGENE HP DNA Transfection Reagent (µl) using 4:1 Ratio 96-well plate(1 well)0.30.1100.10.10.4 48-well plate(1 well)1.00.3300.30.3 1.2 24-well plate(1 well)1.90.5500.50.52 12-well plate(1 well)(1 well)9.42200228 60-mm dish2155005520 10-cm dish55101000101040 T-25 flask2566006624 T-75 flask75202000202080 2.4TroubleshootingObservation Possible Cause RecommendationLow Transfection Efficiency Suboptimal X-tremeGENE HP DNA Transfec-tion Reagent : DNA ratioTitrate optimal X-tremeGENE HP DNA Transfection Reagent : DNAratio. Refer to the text in Section 2.1 “Before you begin”.Insufficient number of cells Determine optimal cell density for each cell type. For most cell types, 70– 90% confluence at transfection is optimal.X-tremeGENE HP DNA Transfection Reagent :DNA complexes did not form wellPrepare complexes in serum-free medium (e.g., Opti-MEM).Do not use siliconized pipet tips or tubes.Do not aliquot the X-tremeGENE HP DNA Transfection Reagent. Incubation time of transfection Determine the optimal incubation time (18 - 72 h). Optimal for most celltypes and plasmids is 24 – 48h.Inhibition by media components Some media components (e.g., polyanions) may influence the transfec-tion.Low volume of X-tremeGENE HP DNA Trans-fection Reagent : DNA complexThe minimum amount of X-tremeGENE HP DNA Transfection Reagentto DNA complex is 100 µl. Complex formation at lower volumes may sig-nificantly decrease the transfection efficiency; refer to the text in Section1, “Special Handling”.High Cytotoxicity Cell density not optimal For each cell type, the optimal density should be determined. For mostcell types, 70 - 90 % confluence at transfection is recommended, butother confluencies may increase cell viability.Cells are cultured in serum-free medium Transfection using X-tremeGENE HP DNA Transfection Reagent in cells cultured in serum-free medium is possible, however, toxicity may behigher when serum is absent.X-tremeGENE HP DNA Transfection Reagent : DNA complexes and cells not mixed well Add X-tremeGENE HP DNA Transfection Reagent dropwise to the cells. Gently rock the dish/plate back and forth and from side to side to evenly distribute the complexes.Plasmid preparation contaminated with endo-toxinTransfected protein is cytotoxic or is produced at high levels Reduced viability or slow growth rates may be due to high levels of pro-tein expression, with cellular metabolism directed toward production of the heterologous protein. Note that the expressed protein may also be cytotoxic at the expressed levels.Too much transfection complex for number of cells Increase the number of plated cells, and/or decrease the total amount of complex added to the cells.3.Additional Information on This ProductQuality ControlEach lot of X-tremeGENE HP DNA Transfection Reagent is tested using established quality control procedures.

转染试剂使用注意事项
转染试剂使用注意事项1.细胞密度:转染DNA(质粒)时,细胞密度为80-100%,转染RNA(siRNA或miRNA)时,细胞密度为60-80%,具体细胞密度必须结合考虑核酸种类、转染试剂种类和细胞生长密度极限;2.DNA用量:0.5-1ug/孔(以24孔板为例),具体用量根据转染效率检测实验确定;3.RNA用量:10-30 pmol/孔(以24孔板为例),具体用量根据转染效率检测实验确定;4.转染试剂的用量:转染试剂说明书推荐了一个使用范围,具体用量根据转染效率检测实验确定;5.根据转染效率检测实验确定核酸的用量及转染试剂的用量(核酸与转染试剂的比例关系),转染效率检测实验一般在24孔板中进行,其他格式的培养器皿请根据底面积的比例(表1)进行计算;6.转染试剂使用前才从4℃中取出,取用前,先短暂离心(转速达到3000RPM时即可停止),然后放在涡旋振荡器上点动混匀三次,每次持续1秒,混匀后短暂离心(转速达到3000RPM时即可停止),上述措施是为了混匀转染试剂,保证使用效果,使用后立即放回4℃保存;7.核酸和转染试剂分别用Opti-MEM(这是专用的转染稀释培养基,如果没有Opti-MEM,可以用细胞对应的基础培养基代替)稀释,稀释的核酸可以通过弹匀,吹打均匀,颠倒混匀或涡旋点动混匀(三次,每次持续1秒),稀释的转染试剂可以通过弹匀,颠倒混匀或涡旋点动混匀(三次,每次持续1秒),不可使用吹打均匀;混匀后均需短暂离心;8.把稀释的核酸和稀释的转染试剂复合混匀时,应该把稀释的核酸加入稀释的转染试剂中(顺序不可调转);加入后立即进行(不要耽搁)弹匀或颠倒混匀(稀释的核酸和稀释的转染试剂一旦复合,转染复合物的形成立即启动,如果不及时混匀,所形成的转染复合物的效率就会很低),先不进行短暂离心,待所有的管子复合完毕后,在一起进行涡旋点动混匀三次,每次持续1秒,然后短暂离心;9.转染复合物孵育形成时尽量避光室温或37℃放置;10.如果进行RNA转染时,尽量使用无酶及灭菌处理的耗材;11.Opti-MEM用量参照转染说明书建议的用量;表1:资料仅供参考!!!。
转染技术要点及转染试剂的选择
[watermark]转染技术要点及转染试剂的选择转染技术是指将外源分子如DNA,RNA等导入真核细胞的技术,它是研究基因表达调控,突变分析等的常规工具。
随着功能研究的兴起,其应用越来越广泛。
以下就向大家介绍一些转染的技术要点及市面上主要的转染试剂类型的选择。
常规转染技术可分为两大类,一类是瞬时转染,一类是稳定转染(永久转染)。
前者外源DNA/RNA不整合到宿主染色体中,因此一个宿主细胞中可存在多个拷贝数,产生高水平的表达,但通常只持续几天,多用于启动子和其它调控元件的分析。
一般来说,超螺旋质粒DNA转染效率较高,在转染后24-96小时内(依赖于各种不同的构建)分析结果,常常用到一些报告系统如荧光蛋白,β半乳糖苷酶等来帮助检测。
后者也称稳定转染,外源DNA既可以整合到宿主染色体中,也可能作为一种游离体(episome)存在。
尽管线性DNA比超螺旋DNA转入量低但整合率高。
外源DNA整合到染色体中概率很小,大约1/104转染细胞能整合,通常需要通过一些选择性标记,如来氨丙基转移酶(APH;新霉素抗性基因),潮霉素B磷酸转移酶(HPH),胸苷激酶(TK)等反复筛选,得到稳定转染的同源细胞系。
转染效率收多种因素影响,主要因素有下面几个:1. 细胞培养物健康的细胞培养物是成功转染的基础。
不同细胞有不同的培养基,血清和添加物。
低的细胞代数(<50)能确保基因型不变。
高的转染效率需要一定的细胞密度,一般的转染试剂都会有专门的说明。
推荐在转染前24小时分细胞,这将提供正常细胞代谢,增加对外源DNA摄入的可能。
一定要避免细菌,支原体或真菌的污染。
2. 血清大多数培养基在使用前需要加血清。
胎牛血清(FCS)经常用到,便宜一点的有马或牛血清。
通常的,血清是一种包含生长因子及其它辅助因子的不确切成分的添加物,对不同细胞的生长作用有很大的差别。
血清质量的变化直接影响转染效率。
因此在转染前建议先测(转右)试出对细胞生长良好的血清批号,转染时用同一批号的血清,并同时做负对照(不加转染试剂及外源DNA)以测试细胞生长是否正常。

Each plasmid should represent at least 10% of the total DNA amount per well/plate.The following conditions are given per 100 mm dish. For other culture format, please refer to Table 2. For optimization, please refer to Table 3.1.Dilute 10 µg total DNA amount into 500 µl jetPRIME®buffer (supplied). Mix by vortexing.2.Add 20 µl jetPRIME®, vortex for 10 s, spin down briefly.3.Incubate for 10 min at RT.4.Add 500 µl of transfection mix per dish drop wise onto the cells in serum containing medium,and distribute evenly.5.Gently rock the dish back and forth and from side to side.6.Eventually replace transfection medium after 4 h by cell growth medium and return the dish tothe incubator.7.Incubate 24 to 72 h and proceed to virus purification and titration.1.4OPTIMIZATION GUIDELINESTransfection conditions should be optimized for each tested cell line according to the conditions detailed below (Table 3). Specific conditions for many cell lines can be found in our cell transfection database, following this link: /technical-resources/cell-line-database/You may adjust the volume of reagent and/or the amount of DNA. The volume of jetPRIME® may range between 2 to 3 µl per µg of DNA depending on the transfected cell line (1:2 and 1:3 DNA to jetPRIME®ratio (w/v)). The amount of DNA may range between 0.5 X and 1.5 X, X being the amount indicated in Table 2.Due to the high performance of jetPRIME® reagent (onto HeLa and HEK-293 cells for example), you may decrease the amount of plasmid DNA down to 0.5 X (Table 3).}CPT114vJ (March 2015)6jetPRIME® DNA & siRNA Transfection ReagentTable 3: Transfection optimization guidelines*Prepare a master mix of minimum 50 µl to allow accurate pipetting and homogenous preparation of thecomplexes.2 siRNA TRANSFECTION PROTOCOL2.1 CELL SEEDINGFor optimal siRNA transfection conditions, we recommend using cells which are 50% confluent at the time of transfection. Typically, for experiments in 6-well plates, 100 000 to 150 000 cells are seeded per well in 2 ml of growth medium 24 h prior to transfection.
