細(xi)(xi)(xi)胞(bao)培(pei)養(yang)技(ji)術(shu)屬于細(xi)(xi)(xi)胞(bao)工程范疇(chou)，細(xi)(xi)(xi)胞(bao)工程包括細(xi)(xi)(xi)胞(bao)融合(he)技(ji)術(shu)、單克隆(long)抗(kang)體的(de)制備、核移植技(ji)術(shu)（克隆(long)）等,而這些技(ji)術(shu)中(zhong)都(dou)有(you)細(xi)(xi)(xi)胞(bao)培(pei)養(yang)過程,所以說細(xi)(xi)(xi)胞(bao)培(pei)養(yang)是生物(wu)學(xue)研究(jiu)的(de)zui基(ji)本技(ji)術(shu)之(zhi)一。

上海慧穎生物供應LTEP-a-2 肺腺(xian)癌(ai)細胞，活性好、存活率(lv)高。隨著細胞生物學(xue)尤其是干細胞研究的(de)(de)快速(su)發展，在(zai)細胞治(zhi)療領域已經進(jin)行了大量的(de)(de)探索，取(qu)得了一系列的(de)(de)令人(ren)振(zhen)奮的(de)(de)成(cheng)果，且部分基礎研究成(cheng)果已經在(zai)心(xin)血(xue)管(guan)系統(tong)疾(ji)病(bing)(bing) 、神經系統(tong)疾(ji)病(bing)(bing)、肌(ji)肉骨(gu)骼相關(guan)疾(ji)病(bing)(bing)、糖尿(niao)病(bing)(bing)等。

養(yang)細胞經驗分享：

1.細(xi)(xi)胞(bao)形態觀察。細(xi)(xi)胞(bao)膜(mo)是(shi)每天必須(xu)觀察的(de)(de)(de)，看是(shi)否清(qing)晰，細(xi)(xi)胞(bao)的(de)(de)(de)死(si)亡往往是(shi)從細(xi)(xi)胞(bao)膜(mo)的(de)(de)(de)破裂開始的(de)(de)(de)，早期的(de)(de)(de)表現就(jiu)是(shi)細(xi)(xi)胞(bao)膜(mo)某一(yi)點出現欠完整或者毛發影。

2.細(xi)胞往往會有“抱(bao)團”現(xian)象，抱(bao)團生(sheng)長或(huo)死亡(wang)，個(ge)人認(ren)為應該勤換(huan)液或(huo)傳代，盡量避 免細(xi)胞抱(bao)團。

3.細(xi)胞生長(chang)迅速(su)，強烈建(jian)議用(yong)較大(da)的(de)培養(yang)瓶養(yang)，用(yong)小瓶養(yang)的(de)話(hua)，換液不及時，很容易死 亡(wang)。細(xi)胞的(de)生長(chang)速(su)度一般為(wei)(wei)2天左右就需要(yao)傳代，并(bing)且(qie)一般為(wei)(wei)一傳三，或一傳四。

4.培養液(ye)：1640|DMEM|MEM|IMDM|a-MEM培養液(ye)，1L一般加碳酸氫鈉2g，并加雙抗(kang)，胎牛血清(qing)濃度*為12%，zui低(di)不低(di)于10%，有些細胞(bao)對胎牛血清(qing)高度依賴，比如WRO細胞(bao)，HT-22細胞(bao)，HA-VSMC細胞，NK-92細胞等。培養液(ye)PH應調為7.20-7.40之間。

5.防污染。L-02細胞(bao)生(sheng)長(chang)迅(xun)速，較少發生(sheng)污染，但常規措施應該做(zuo)好。比如無菌操作，酒精 消毒(du)等，培(pei)養瓶(ping)口建(jian)議過火，包括瓶(ping)蓋，應過火4秒左右。

6.凍(dong)存。-20一小時，-80次夜，液(ye)氮(dan)長(chang)期(qi)保存。強烈建議液(ye)氮(dan)長(chang)期(qi)保存，盡量(liang)不要在(zai)-80長(chang)期(qi) 保存，死亡率很高。

7.復蘇(su)。調節水浴箱溫度為42℃，并(bing)提(ti)前在(zai)試管(guan)(guan)內(nei)(nei)放置10倍培養液，使培養液溫度與(yu)室(shi)溫一 致。1分鐘內(nei)(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)(nei)，動作要輕，從試管(guan)(guan)管(guan)(guan)底開始慢慢上提(ti) 移液管(guan)(guan)，使細胞在(zai)培養液內(nei)(nei)分布均勻(yun)，離心，洗2次(ci)。
