hello,
最近需要用cell surface marker 细胞染色,sort positive 的细胞,然后重新plate
培养。每次sort完细胞,重新plate以后,细胞总是大量死亡。希望大家有什么建议。
下面是我的protocol
Trypsin cells. Stop reaction. collect cells. Wash once with PBS+0.2% BSA.
Staining cells in the dark at RT for 25 min. Staining buffer: PBS (w/o Ca2+
Mg2+) + 0.2% BSA+ 0.09% NaN3.
Wash three twice. (500gX5 min every time)
Resuspend cells in Staining buffer. Sort cells..
Replate positive cells.
