CHO-K1细胞-悬浮培养细胞是指将 复苏CHO-K1细胞转入T25 cm2细胞培养瓶,以F12K基础培养基添加10%血清培养,待细胞长满单层后,加入 0.25 % 胰蛋白酶消化,传代至装有完全培养基的T25 cm2细胞培养瓶(Corning)中继续培养,当细胞铺满瓶底时,即得贴壁 CHO-K1 细胞。

CHO-K1细胞-悬浮培养细胞

    CHO-K1细胞-悬浮培养细胞是指将复苏CHO-K1细胞转入T25 cm2细胞培养瓶,以F12K基础培养基添加10%血清培养,待细胞长满单层后,加入 0.25 % 胰蛋白酶消化,传代至装有完全培养基的T25 cm2细胞培养瓶(Corning)中继续培养,当细胞铺满瓶底时,即得贴壁 CHO-K1 细胞。取贴壁CHO-K1 细胞,换液,加入15 mL含血清的完全基和 15 mL无血清CHO-K1专用培养基,2天后吸出一半培养液,加入等量的无血清CHO-K1,每2天重复一次此操作,直到胎牛血清浓度低于 1 %后,以基础培养基B001 继续培养,即培养基中血清浓度依次以 5 %,2 .5 %,1.25%,0.625 %,0 %降低。细胞在无血清CHO-K1专用培养基中密度达到5 ×106cells/ mL时,即得悬浮 CHO-K1 细胞。培养条件:传代培养条件:37±1℃,120rmp,6.0%CO2
