摘要
以BALB/C小鼠胚胎成纤维细胞(BALB/C3T3)作为靶细胞,经20mmol/L醋酸钠平衡后的CM-Sepharose(CMS)吸附过的胎牛血清作为基础培养血清,应用[3-(4,5-dimethylthi-azolyl)-2,5-diphenyltetrazoliumbromide,MTT]方法测定血小板源生长因子(platelet-derivedgrowthfactor,PDGF)诱导细胞增殖的生物活性.结果表明,该方法具有良好的量效关系,且精确度、重现性均较高.
The activity of platelet-derived growth factor( PDGF)was determined by the method of 3-(4,5-dimethylthiazolyl)-2,5-diphenyltetrazolium bromide(MTT).BALB/C embryo fibroblast 3T3 cells were taken as the target cells.The cow foetus serum (CFS) absorbed by carboxymethylcellulose-sephose (CMS) was taken as a basic cultural serum.The results indicated that this method was more accurate and repeatable,and had a good relationship between the effects and quantities
