实例说明PolyJet™体外DNA转染试剂对常见细胞系优异的转染效率。
PolyJet™转染试剂和lipofectamine
Plus转染试剂对中国仓鼠卵巢(CHO)细胞转染效率的比较。分别使用PolyJet™ (左图)和lipofectamine Plus (右图)将HA标记的β微管蛋白cDNA转染入中国仓鼠卵巢细胞。异硫氰酸荧光素(FITC)标记的抗HA标记的抗体被用来结合HA-β微管蛋白(绿色),DM1a抗体被用来检测内源性的β微管蛋白,它连接着罗丹明标记的二抗(红色)探针。上述图片是由德克萨斯州休斯顿医学院(University
of Texas at Houston Medical School)的Dr. Shang Yin友情提供的。
PolyJet™试剂和一款领先产品Lipofectamine
2000对HEK293FT细胞染效率的比较。分别使用PolyJet™(左图)和Lipofectamine
2000(右图)将GFP载体(pEGFPN3)转染入HEK293FT细胞。转染24小时后,通过尼康Eclipse荧光显微镜检查细胞的转染效率。
PolyJet™ 试剂和市场主导品牌产品Lipofectamine
2000对HepG2细胞转染效率的比较。分别使用PolyJet™ (左图)和Lipofectamine 2000(右图)将GFP载体(pEGFPN3)转染入HepG2 细胞。转染24小时后,通过尼康Eclipse荧光显微镜检查细胞的转染效率。
PolyJet™和Fugene HD对MDCK细胞染效率的比较。分别使用PolyJet™(左图)和Fugene
HD (右图)按照生产制造商的科学实验步骤将绿色荧光蛋白(GFP)DNA转导入MDCK细胞。转染48小时后,在荧光显微镜下观察GFP和DAPI染色。上面的图片是由NYU医学中心的Ge
Zhou博士友情提供的。
PolyJet™试剂和市场主导品牌产品Lipofectamine
2000对MDCK细胞转染效率的比较。MDCK细胞是较难转染的细胞系。使用我们专有的细胞转染操作程序,PolyJet™
(左图)能高达70% GFP阳性细胞对比Lipofectamine 2000 (右图)大约 5%的阳性效率。分别使用由PolyJet™
(左图)和Lipofectamine 2000 (右图)将GFP载体(pEGFPN3)转染入MDCK细胞。转染36小时后,通过尼康Eclipse荧光显微镜检查转染效率。
PolyJet™试剂同市场主导品牌产品之一Fugene
HD对LNCap细胞转染效率的比较。分别使用PolyJet™ (左图)和Fugene HD(右图)将GFP载体(pEGFPN3)转染入LNCap细胞。转染24小时后,通过尼康Eclipse荧光显微镜检查转染效率。
PolyJet™试剂对神经细胞系Neuro2A有较高的转染效率。使用PolyJet™体外DNA转染试剂将pEGFPC1质粒转染入Neuro2A细胞。转染24小时后,通过尼康Eclipse荧光显微镜观察Neuro2A细胞的DIC影像(左)和荧光影像(右)。
PolyJet™ DNA体外转染试剂和Lipofectamine 2000在原代小鼠皮肤成纤维细胞上的细胞毒性的比较。小鼠成纤维细胞与指定的转染试剂/pEGFPC1
(DNA)混合物在无血清DMEM高糖培养基孵育4小时,然后用全血清培养基替代。转染24小时后,细胞的尼康Eclipse荧光显微镜DIC相位成像图。

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.
-----Tiffany Wallace, Ph.D., June 9, 2009, NCI / NIH
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.
------Feng Qiao, Ph.D., Jun 12, 2009, 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.
-----Stephanie Murphy, Ph.D., June 29, 2009, Dartmouth College
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., August11, 2009, UMASS
I tested PolyJet and it looks great on MDCK. We placed order. Thank you!
-------Ge Zhou, Ph.D., August 12, 2009, 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.
