鄙人实验室有2个人主要做exo,一个是师兄(其实和我一届,但年龄比我大很多),一个是我。
师兄平时要上临床,因此很忙,做的是DC-exo-Cardiomyocytes,未涉及很多机制,匆匆做了点现象,就投稿了。
被拒了。。。
其中一条拒稿意见是这样的:
The method of exosome isolation - ExoQuick is a well accepted method of exosome isolation. The yield is high, but the specificity is low. This paper (Lobb RJ Optimized exosome isolation protocol for cell culture supernatant and human plasma, J Extra Vesc, 2015) nicely sums up the problem: "In conclusion, both ExoQuickTM and Exo-spinTM have significantly more non-exosomal protein contamination as evidenced by the particle/protein ratio combined with increased exosome marker expression in qEV and density gradient isolations." This is borne out by your suspiciously high yield of protein from exosomes 10+ ug. Therefore, a number of non-exosomes may also be present in the tail-vein injections resulting in signaling from these activated dendritic cells. I encourage you to make note of this methodologic limitation in your conclusion.
用kit的童鞋们,都要小心啦。。。

鄙人也基本做完了,正在整理数据写文章。
本着21世纪的“互联网分享精神”,打算在下次小聚时与大家分享我所有的结果。
