有限稀釋法的程序
①制備飼養(yǎng)細(xì)胞懸液
②轉(zhuǎn)染了重組質(zhì)粒后的細(xì)胞計(jì)數(shù),并調(diào)細(xì)胞數(shù)在1~5×103/ml
③取130個(gè)細(xì)胞放入6.5ml含飼養(yǎng)細(xì)胞完全培養(yǎng)液,即20個(gè)細(xì)胞/ml,100μl/孔加A、B、C三排為每孔2個(gè)細(xì)胞。余下2.9ml細(xì)胞懸液補(bǔ)加2.9ml含飼養(yǎng)細(xì)胞的完全培養(yǎng)液,細(xì)胞數(shù)為10個(gè)/ml,100μl/孔加D、E、F三排,為每孔1個(gè)細(xì)胞。余下2.2ml細(xì)胞懸液補(bǔ)加2.2ml含飼養(yǎng)細(xì)胞的完全培養(yǎng)液,細(xì)胞數(shù)5個(gè)/ml,100μl/孔,加G、H兩排,為每孔0.5個(gè)細(xì)胞。
④培養(yǎng)4~5天后,在倒置顯微鏡上可見(jiàn)到小的細(xì)胞克隆,補(bǔ)加完全培養(yǎng)液200μl/孔。
⑤第8~9天時(shí),肉眼可見(jiàn)細(xì)胞克隆。
