細(xì)胞培養(yǎng) RPMI Medium 1640
平時(shí)研究用的細(xì)胞,有需要冷凍保存。冷凍的過(guò)程稱為凍存,把凍上的細(xì)胞化開(kāi)的過(guò)程叫細(xì)胞復(fù)蘇。細(xì)胞復(fù)蘇是一簡(jiǎn)單的試驗(yàn)操作,但操作中有許多需要注意的事項(xiàng),在實(shí)驗(yàn)操作中注意細(xì)小問(wèn)題,才能使復(fù)蘇后的細(xì)胞狀態(tài)保持良好。
細(xì)胞復(fù)蘇實(shí)驗(yàn)準(zhǔn)備:
主要器材:一次性滴管、打火機(jī)、酒精燈、大鑷子、中鑷子、記號(hào)筆、廢液缸、封口膜、剪子。
主要試劑: PBS、培養(yǎng)液、消化酶(胰酶)、75%酒精、雙抗。
PBS配制:NaCL :4g KCL:0.1g Na2HPO4 :1.745g KH2PO4 :0.1g
三蒸水: 500mL,溶解后高壓滅菌。
培養(yǎng)基配制:5mL雙抗、50mL血清,加入培養(yǎng)基中。
細(xì)胞復(fù)蘇操作步驟:
1.佩戴眼鏡和手套,從液氮罐中取出安瓿或冷凍管。
2.迅速放入38℃水浴中,并不時(shí)搖動(dòng),在1分鐘內(nèi)使其*融化,然后在無(wú)菌下取出細(xì)胞。
3.在1000r/min速度下離心5~10分鐘,棄去上層液,加入適量培養(yǎng)液后接種于培養(yǎng)瓶中,接種濃度1×109/L,置37℃溫箱靜置培養(yǎng),次日更換一次培養(yǎng)液,繼續(xù)培養(yǎng),觀察生長(zhǎng)情況。若細(xì)胞密度較高,及時(shí)傳代?;驘o(wú)需離心直接將細(xì)胞加入瓶中,并加入培養(yǎng)基貼壁培養(yǎng)12~24小時(shí)后,充去上清,換入新鮮培養(yǎng)基繼續(xù)培養(yǎng)。
