養細(xi)胞經驗分享(xiang)：

1.細胞(bao)形態觀(guan)察。細胞(bao)膜(mo)(mo)是(shi)每天必(bi)須觀(guan)察的(de)，看是(shi)否(fou)清(qing)晰，細胞(bao)的(de)死(si)亡(wang)往(wang)往(wang)是(shi)從細胞(bao)膜(mo)(mo)的(de)破裂(lie)開始的(de)，早期的(de)表(biao)現就是(shi)細胞(bao)膜(mo)(mo)某一點出現欠完整或者毛發影。

2.細胞往(wang)往(wang)會有“抱團(tuan)”現象，抱團(tuan)生(sheng)長或死亡，個人認為應(ying)該(gai)勤(qin)換液或傳代，盡量避 免(mian)細胞抱團(tuan)。

3.細(xi)胞生長迅(xun)速，強(qiang)烈建(jian)議(yi)用(yong)較大的培養(yang)(yang)瓶養(yang)(yang)，用(yong)小瓶養(yang)(yang)的話，換液(ye)不及時，很容易死 亡。細(xi)胞的生長速度一般為2天左右就需要傳(chuan)代，并且(qie)一般為一傳(chuan)三，或一傳(chuan)四。

4.培(pei)養(yang)(yang)液：1640|DMEM|MEM|IMDM|a-MEM培(pei)養(yang)(yang)液，1L一般(ban)加(jia)碳酸氫(qing)鈉2g，并加(jia)雙抗，胎(tai)牛血清(qing)濃度*為12%，zui低不低于10%，有些細(xi)(xi)胞對(dui)胎(tai)牛血清(qing)高度依賴，比如(ru)WRO細(xi)(xi)胞，HT-22細(xi)(xi)胞，HA-VSMC細胞(bao)，NK-92細胞(bao)等。培養液PH應調為7.20-7.40之(zhi)間。

5.防污(wu)染。L-02細胞生(sheng)長(chang)迅速，較少發(fa)生(sheng)污(wu)染，但常規措施應該做好。比如無菌(jun)操作，酒精(jing) 消毒(du)等，培養瓶口建議過火(huo)，包括瓶蓋，應過火(huo)4秒左(zuo)右(you)。

6.凍(dong)存(cun)。-20一小時，-80次夜，液(ye)氮長(chang)(chang)期保(bao)(bao)存(cun)。強(qiang)烈建議液(ye)氮長(chang)(chang)期保(bao)(bao)存(cun)，盡量不要在-80長(chang)(chang)期 保(bao)(bao)存(cun)，死亡率很高(gao)。

7.復蘇。調節水浴箱溫度為42℃，并提前在(zai)試管(guan)(guan)內(nei)放置10倍培(pei)(pei)養液(ye)(ye)，使(shi)培(pei)(pei)養液(ye)(ye)溫度與室溫一 致。1分(fen)鐘內(nei)融化細胞(禁(jin)止(zhi)搖晃凍存管(guan)(guan))，移取至試管(guan)(guan)內(nei)，動作要(yao)輕，從試管(guan)(guan)管(guan)(guan)底開始慢慢上提 移液(ye)(ye)管(guan)(guan)，使(shi)細胞在(zai)培(pei)(pei)養液(ye)(ye)內(nei)分(fen)布(bu)均勻，離心，洗2次。
