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 U+ U/ J+ t! h) b# y
Subculturing: Protocol: Subcultures are prepared by scraping.
7 A2 ?! ~ S3 n/ F* w& y! k' 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. 3 c# B# F$ J2 x# _
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended

' Z3 W. S; u* y! x/ G% c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。 |
