哈哈,同道。腺病毒载体转染UCB-MSCs。我还没做,这是文献里面的步骤:Third-passage cells were transduced with adenovirus containing either green fluorescent protein (GFP) (AdGFP) or both GFP and SOX9 (AdSOX9). The lanthofection procedure was described previously by Palmer et al. Briefly, virus was diluted in 8mL DMEM per 300 cm2 flask to about 10,000 viral particles=cell (which is approximately 100 MOI病毒感染), and LaCl3 (Sigma-Aldrich GmbH, Buchs, Switzerland) was added dropwise to a final concentration of 100 mM. After 30 min of incubation the solution was added to the flasks containing 20mL DMEM with 10% fetal bovine serum and incubated overnight. On the average 95% transduction efficiency was reached with this method.1 O! h# o, ^( _# Q
第三代细胞转染含绿色荧光蛋白(GFP)(AdGFP)或GFP和SOX9(AdSOX9)的腺病毒. Palmer等前面描述的lanthofection程序。简言之,病毒在每300 cm2的培养瓶8mL DMEM培养液稀释,病毒颗粒约10000=细胞(大约是100MOI病毒感染复数),和氯化镧(Sigma - Aldrich公司的有限责任公司,布克斯瑞士)滴加至终浓度100毫摩。30分钟孵育后溶液添加到含20ml的含10%胎牛血清DMEM的培养瓶孵育过夜。用这种方法转转染效率平均达到95%。
