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:, S; D5 I @3 G4 f
Subculturing: Protocol: Subcultures are prepared by scraping.: l) b# a8 X1 u) s9 q5 e
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. % z: v+ g) |1 y
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended 0 J; I9 d. U, B
Medium Renewal: Replace or add medium every 2 to 3 days.
1 r9 G* T7 n$ h* V, R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。 |
