Description
Based on our proprietary polymer synthesis technology, PolyJet� DNA In Vitro Transfection Reagent is formulated as a biodegradablepolymer基于DNA转染试剂,可确保对HEK293的有效和可重复转染,COS-7, NIH-3T3, HeLa, CHO and a broad ranges of hard-to-transfect mammalian celLS。PolyJet�试剂能够以非常低的浓度在电泳过程中固定DNA迁移,并在RT的5分钟内形成转染复合物。该试剂的一个显着特征是转染复合物内吞作用后聚合物的快速和完全降解(图1),导致细胞毒性少得多。Polyjet r试剂(1.0 mL)足以在24个井板中进行〜667次转染或6个井板中的〜333转染,为领先产品提供了一种非常实惠的替代品,用于转染各种常用和难以转移的哺乳动物细胞。

Examples Showing Transfection Efficiency of PolyJet� DNA In Vitro Transfection Reagent on Commonly Used Cells
Transfection efficiency comparison of PolyJet� vs. lipofectamine Plus on Chinese Hamster Ovary (CHO) cells.HA tagged beta-tubulin cDNA was delivered into CHO cells with PolyJet� (left panel) and lipofectamine Plus (right panel) respectively. FITC conjugated antibody against HA tag was utilized to pick up HA-beta-tubulin (Green) while a DM1a antibody was used to detect endogenous alpha-tubulin followed by probing with rhodamine conjugated secondary antibody (Red).

A comparison showing transfection efficiency of PolyJet� reagent vs. a leading product, Lipofectamine 2000 on MDCK cells.MDCK cells are notoriously hard to transfect. With proprietary "Shaved Cell Transfection" protocol, PolyJet� (left panel) gives up to 70% GFP positive cells vs. Lipofectamine 2000 (right panel) around 5% efficiency. MDCK cells were transfected with GFP vector (pEGFP-N3) by PolyJet� (left panel) and Lipofectamine 2000 (right panel) respectively. The cells were visualized by Nikon Eclipse Fluorescence microscope 36 hours post transfection

Sorry for sooo big delay, but now I am totally in love with PolyJet. I have used PolyJet for a while on mouse ESCs with relatively good efficiency 50~70%.
--------Marina Pryzhkova, Ph.D., JHU
PolyJet Transfection Reagent worked equally as well as lipofectamine 2000, with little evidence of cell death on 293, PC-3 and 22RV1 cells. I will defiantly consider switching over.
-----蒂法尼·华莱士(Tiffany Wallace)博士,NCI / NIH
我只与测试样品(PolyJet)和LiPO2000并排进行了cos-7细胞的GFP转染。结果非常好。Polyjet甚至比L2K更好。
------Feng Qiao, Ph.D., NEI / NIH
I tested the sample of PolyJet on my NIH-3T3 mouse fibroblasts this weekend. The results were much better than Lipofecatmine LTX. I'm attaching a powerpoint slide with my results (I did not quantify the % transfection efficiency, but the pictures get the point across). I found that the protocol for difficult-to-transfect cell lines worked better than the standard protocol.
-----斯蒂芬妮·墨菲(Stephanie Murphy)博士,达特茅斯学院
I had chance to try your product finally. It was great success. I used HeLa cells and got 10% transfection efficiency (<0.1% for Lipofectamine). Thank you! I was wondering if I also try GenJet� Plus DNA In Vitro Transfection Reagent? According to your website, the reagent works better than regular PolyJet.
-------Yumi Uetake, Ph.D., UMASS
I tested PolyJet and it looks great on MDCK. We placed order. Thank you!
-------Ge Zhou, Ph.D., NYU
We are happy to provide feedback. PolyJet worked very well for us in HepG2 cells, we got approximately 80% efficiency with pMAX GFP plasmid, by following the conditions in your suggested protocol. We ran a comparison with Lipofectamine, which only showed approximately 20-30% transfection efficiency. We are planning experiments and will be ordering more soon.
