没有养过这种破骨细胞,但是细胞长得快就传代稀释一点。ATCC的说明是:6 h( \4 F! Z9 E* l3 K

For a 75 cm2 flask, remove all but 10 ml culture medium (adjust amount accordingly for other culture vessels). Dislodge cells from the flask substrate with a cell scraper; aspirate and add appropriate aliquots of the cell suspension into new culture vessels. 6 p( d( ?+ K" n: D8 y: c# X

你可以低密度传代,如果还是很快,那很有可能被其他细胞污染,不是原本的RAW,比如从别人要来的,可能被处理过,实验结果就不可靠了。这种现象国内实验室常见的,一般都买新的细胞,不要从别人索取,要不就得有MTA协议的正规获得。作者: sailboat 时间: 2009-6-18 22:15
