产品详情

PolyFect Transfection Reagent采用先进的活化树状多聚物,从多聚物中心向外辐射出带正电荷的氨基基团与DNA 分子结合，为下列细胞株特别优化：COS-7、NIH/3T3、HeLa、293、CHO。

绩效

PolyFect Transfection Reagent保持高效转染率（参见" High transfection efficiencies in CHO and 293 cells"和" PolyFect Reagent with HeLa cells"）。与其他试剂不同的是，PolyFect Transfection Reagent能够在血清存在的情况下进行转染而不降低转染效率。

原理

PolyFect Transfection Reagent是一种特殊活化的树状聚合物。它由从中心发散出分支的球形大分子构成（参见" Activated dendrimer"）。分支终止于带电的氨基，可与带相反电荷的磷酸基相互作用。PolyFect Reagent将DNA聚集成紧密结构（参见 " PolyFect–DNA interaction"），附于细胞表面通过非特异性内吞作用进入细胞。该试剂调节细胞核内pH，抑制核内核酸，从而保证了PolyFect–DNA复合物的稳定性。

程序

PolyFect Transfection Reagent是即用型试剂。转染流程（参见" PolyFect transfection procedure"）简便迅速，只需要将试剂加入到DNA溶液中混合，反应5–10分钟，加入培养基（可以含血清和抗体），将PolyFect–DNA复合物移到细胞上。培养细胞用于基因表达。无需转染后移除复合物或更换及增加培养基，操作简便快速。

高通量转染

使用PolyFect Transfection Reagent进行转染只需少量手动操作且无需移除转染复合物，特别适用于高通量筛选。PolyFect Reagent在高通量转染中转染效率高，可重复性好，细胞毒性低，适用于批量转染。关于在96孔板中对COS-7、NIH/3T3、HeLa、HeLa-S3、293和CHO细胞进行转染的实验方案，请咨询QIAGEN技术支持。

High transfection efficiencies in CHO and 293 cells.

Transfection efficiencies for PolyFect Reagent and 2 lipid-based reagents were compared. Cells cultured in 6-well plates were transfected with a beta-galactosidase-reporter plasmid. The appropriate protocol was used for transfection with PolyFect Reagent. Optimized protocols were used for transfection with Reagents L2 and F; these were: 10 µl Reagent L2 with 3 µg DNA and 15 µl Reagent F with 2 µg DNA for CHO cells, and 10 µl Reagent L2 with 2 µg DNA and 7 µl Reagent F with 3 µg DNA for 293 cells. All transfections were performed in triplicate. Two independent transfection experiments are shown for 293 cells.

FAQ

The recommended amount of DNA being transfected should be split between the different plasmids. For example, if you normally transfect 5 µg of one plasmid, use 2.5 µg each for two plasmids (other proportions of the two plasmids can be used, as long as 5 µg total is maintained) as a starting point for optimization.

QIAGEN Transfection Reagents have been used successfully with many different cell types. For your convenience, we have organized data from researchers who have shared their experimental results with us online in our Transfection Cell Database. Simply type your cell line of interest into the 'Search' field on this page, and find transfection results achieved with various QIAGEN Transfection Reagents. Please note that QIAGEN cannot verify data supplied from outside sources.

You can also submit your own transfection data and obtain a gift as appreciation. In addition you can find on our TransFect Protocol Database transfection protocols for specific cell types and plate formats.

FAQ ID -158

For the transfection of oligonucleotides and/or large vector constructs (>20 kb) using PolyFect Transfection Reagent, we recommend performing optimization trials to determine the optimal Transfection Reagent/DNA ratio. The amounts of DNA and Reagent provided in the PolyFect Transfection Reagent Handbook can be used as a guideline.

We suggest to start optimization using a range between half and twice the recommended amount of PolyFect Transfection Reagent while keeping the DNA amount constant, as well as using half and twice the recommended amount of DNA while keeping the amount of PolyFect Transfection Reagent constant. For increasing the transfection efficiency of adherent cells you can use the Attractene Transfection Reagent, or of primary cells and difficult-to-transfect cells using Effectene Transfection Reagent.
