针对中国仓鼠卵巢(CHO)细胞，PolyJet转染效率同lipofectamine Plus试剂[由Life Technologies公司（BRL）生产的商品化细胞转染试剂，是合成的阳离子脂类DOSPA和DOPE的3：1（w/w）混合物]进行比较。
标记HA的Beta微管蛋白DNA分别加入PolyJet试剂(左图)和lipofectamine Plus试剂 (右图)被输送进仓鼠卵（胞。 HA标记的FITC共轭抗体被用于提取HA-beta微管蛋白 (绿色部分)，而DM1a抗体被用于检测伴随罗丹明共轭二次抗体的内源阿尔法微管蛋白 (红色部分)。上述图片由得克萨斯大学休斯敦医学院的Shang Yin博士友情提供提供。

比较研究（通过MDCK细胞试验，PolyJet试剂的同主导试剂产品Lipofectamine 2000相比后所展示的转染效率）。MDCK属于极难转染的细胞。根据专有“削减细胞转染”协议，PolyJet 试剂(左图) 放弃了70%的GFP阳性细胞，相比之下，Lipofectamine 2000(右图)的效率仅约为5%。MDCK细胞通过分别输入与GFP传染媒介(pEGFP-N3)结合的PolyJet 试剂(左图) 和Lipofectamine 2000(右图)被转染。该细胞在转染后36小时可通过尼康Eclipse荧光显微镜进行观察。

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.

I only did side by side with the testing sample (PolyJet) and Lipo2000 with GFP transfection on COS-7 cells. The result was very good. PolyJet was even better than L2K.

I tested the sample of PolyJet on my NIH-3T3 mouse fibroblasts this weekend. The results were much better than Lipofecatmine LTX. Im 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.

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.

I tested PolyJet and it looks great on MDCK. We placed order. Thank you!

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.
