Product Details

PolyFect Transfection ReagentはCOS-7、NIH/3T3、HeLa、293、CHO細胞へのDNAトランスフェクション用に至適化された活性型デンドリマーテクノロジーを利用しています。

Performance

PolyFect Reagentを用いると、常に高いトランスフェクション効率が得られます（図" CHOおよび293細胞における高いトランスフェクション効率"および" PolyFect Reagentを用いたHeLa細胞へのトランスフェクション"）。PolyFect Transfection Reagentを用いれば、多くのリポソーム試薬とは対照的にトランスフェクション効率が低下することなく血清存在下でのトランスフェクションが可能です。

Principle

PolyFect Transfection Reagentは、特別にデザインされた活性化デンドリマー溶液です。本試薬は、中核から放射状に伸びる分枝を有する既定の球状構造のデンドリマー分子で構成されています（図" 活性化デンドリマー"）。この分子は、プラスに電荷したアミノ基を末端に持ち、これがマイナスに電荷した核酸のリン酸基と相互作用して結合します。PolyFect ReagentはDNAをコンパクトな構造にアセンブルし（図" PolyFect–DNA相互作用"）、それによって細胞表面に結合し、非特異的エンドサイトーシスによって細胞内に取り込まれます。本試薬はエンドソームのpHを緩衝し、エンドソームのヌクレアーゼをpH阻害することによってPolyFect–DNA複合体を安定化させます。

Procedure

PolyFect Transfection Reagentは即使用可能な溶液です。トランスフェクションの操作手順（フローチャート" PolyFect Transfection製法"）は迅速かつ簡単です。PolyFect ReagentをDNA溶液に添加して混合し、5～10分間のインキュベーション後、培養液（血清および抗生物質を含む）を添加し、PolyFect-DNA複合体をピペットで細胞に添加する。細胞は遺伝子発現のためインキュベートします。複合体の除去あるいは培養液の交換の必要がないので、操作は迅速で簡単です。

ハイスループットトランスフェクション

PolyFect Reagentを用いたトランスフェクションは、操作が簡便で、トランスフェクション複合体を除去する必要もないので、ハイスループットスクリーニングには最適なトランスフェクション試薬です。ハイスループットトランスフェクションにおいて、効率および再現性が非常に高く、細胞毒性も低いPolyFect Reagentは、バルクサイズも用意しております。96ウェルプレートにおけるCOS-7、NIH/3T3、HeLa、HeLa-S3、293、CHO細胞のトランスフェクションの至適化済みのプロトコールについては、QIAGENテクニカルサービスにお問い合わせください。

Supporting data and figures

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.
