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: u& y5 r5 J V' D, {
Subculturing: Protocol: Subcultures are prepared by scraping.
1 b( l6 m; J% ^7 E+ SFor 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.

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。 |
