養細胞經(jing)驗分享：

1.細(xi)胞(bao)(bao)(bao)形(xing)態觀(guan)察(cha)。細(xi)胞(bao)(bao)(bao)膜是每天必須觀(guan)察(cha)的(de)(de)，看是否(fou)清晰，細(xi)胞(bao)(bao)(bao)的(de)(de)死亡往(wang)(wang)往(wang)(wang)是從(cong)細(xi)胞(bao)(bao)(bao)膜的(de)(de)破裂(lie)開始的(de)(de)，早期(qi)的(de)(de)表(biao)現(xian)就是細(xi)胞(bao)(bao)(bao)膜某(mou)一點出現(xian)欠完整或者毛發影(ying)。

2.細(xi)(xi)胞往往會有“抱團”現象(xiang)，抱團生長或(huo)死亡，個人認(ren)為(wei)應該勤換液或(huo)傳代，盡量避 免細(xi)(xi)胞抱團。

3.細胞(bao)生(sheng)(sheng)長迅速，強烈建議用較(jiao)大的(de)培養瓶養，用小(xiao)瓶養的(de)話，換(huan)液(ye)不及時(shi)，很容(rong)易死 亡。細胞(bao)的(de)生(sheng)(sheng)長速度(du)一(yi)(yi)般為2天左(zuo)右就需要傳(chuan)代，并(bing)且一(yi)(yi)般為一(yi)(yi)傳(chuan)三，或一(yi)(yi)傳(chuan)四。

4.培養(yang)液：1640|DMEM|MEM|IMDM|a-MEM培養(yang)液，1L一(yi)般(ban)加碳酸氫鈉2g，并(bing)加雙抗(kang)，胎牛(niu)血清濃度*為12%，zui低(di)不低(di)于10%，有些細胞對胎牛(niu)血清高度依賴(lai)，比如(ru)WRO細胞，HT-22細胞，HA-VSMC細胞(bao)，NK-92細胞(bao)等。培養(yang)液PH應調為7.20-7.40之(zhi)間。

5.防污(wu)染(ran)。L-02細胞生長迅速，較少發生污(wu)染(ran)，但常規措施應該做好(hao)。比(bi)如無菌操作，酒精 消毒等，培養瓶口建議過火(huo)，包括(kuo)瓶蓋，應過火(huo)4秒左右。

6.凍存(cun)(cun)。-20一小(xiao)時，-80次夜，液氮長(chang)期保(bao)存(cun)(cun)。強烈建議液氮長(chang)期保(bao)存(cun)(cun)，盡量不要在(zai)-80長(chang)期 保(bao)存(cun)(cun)，死亡率很高。

7.復蘇。調節水浴(yu)箱(xiang)溫(wen)度為42℃，并提前在試管(guan)(guan)內放置10倍培(pei)養液(ye)，使培(pei)養液(ye)溫(wen)度與(yu)室溫(wen)一 致。1分鐘(zhong)內融化細胞(禁止搖晃凍存管(guan)(guan))，移(yi)取至試管(guan)(guan)內，動作要(yao)輕(qing)，從試管(guan)(guan)管(guan)(guan)底開始慢慢上提 移(yi)液(ye)管(guan)(guan)，使細胞在培(pei)養液(ye)內分布均(jun)勻，離心，洗2次。
