CHO-K1細胞-懸浮培養(yǎng)細胞

    CHO-K1細胞-懸浮培養(yǎng)細胞是指將復蘇CHO-K1細胞轉(zhuǎn)入T25 cm2細胞培養(yǎng)瓶，以F12K基礎培養(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天重復一次此操作，直到胎牛血清濃度低于 1 %后，以基礎培養(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
