CHO-K1細胞-懸浮培養(yǎng)細胞
CHO-K1細胞-懸浮培養(yǎng)細胞是指將復(fù)蘇CHO-K1細胞轉(zhuǎn)入T25 cm2細胞培養(yǎng)瓶,以F12K基礎(chǔ)培養(yǎng)基添加10%血清培養(yǎng),待細胞長滿單層后,加入 0.25 % 消化,傳代至裝有培養(yǎng)基的T25 cm2細胞培養(yǎng)瓶(Corning)中繼續(xù)培養(yǎng),當細胞鋪滿瓶底時,即得貼壁 CHO-K1 細胞。取貼壁CHO-K1 細胞,換液,加入15 mL含血清的基和 15 mL無血清CHO-K1專用培養(yǎng)基,2天后吸出一半培養(yǎng)液,加入等量的無血清CHO-K1,每2天重復(fù)一次此操作,直到胎牛血清濃度低于 1 %后,以基礎(chǔ)培養(yǎng)基B001 繼續(xù)培養(yǎng),即培養(yǎng)基中血清濃度依次以 5 %,2 .5 %,1.25%,0.625 %,0 %降低。細胞在無血清CHO-K1專用培養(yǎng)基中密度達到5 ×106cells/ mL時,即得懸浮 CHO-K1 細胞。培養(yǎng)條件:傳代培養(yǎng)條件:37±1℃,120rmp,6.0%CO2
