細(xi)胞(bao)培(pei)(pei)養(yang)技(ji)術屬(shu)于(yu)細(xi)胞(bao)工程范疇(chou)，細(xi)胞(bao)工程包括細(xi)胞(bao)融合技(ji)術、單克隆(long)抗體的制(zhi)備、核移(yi)植技(ji)術（克隆(long)）等,而(er)這些技(ji)術中都(dou)有(you)細(xi)胞(bao)培(pei)(pei)養(yang)過程,所以說(shuo)細(xi)胞(bao)培(pei)(pei)養(yang)是生(sheng)物學研究的zui基本技(ji)術之一(yi)。

上海慧穎生物供應GP2-293人胚腎上皮包裝細胞，進口胎牛血(xue)清培養(yang)，活(huo)性(xing)好、存活(huo)率高(gao)。隨著細(xi)胞生物學尤(you)其是干(gan)細(xi)胞研究的(de)快速發(fa)展，在(zai)(zai)細(xi)胞治療領域已經(jing)進行(xing)了大量(liang)的(de)探索，取(qu)得了一(yi)系(xi)列的(de)令人振奮的(de)成(cheng)(cheng)果(guo)，且部分(fen)基礎研究成(cheng)(cheng)果(guo)已經(jing)在(zai)(zai)心血(xue)管系(xi)統疾病(bing)(bing) 、神(shen)經(jing)系(xi)統疾病(bing)(bing)、肌肉(rou)骨骼相關疾病(bing)(bing)、糖尿病(bing)(bing)等。

養細胞(bao)經驗(yan)分(fen)享：

1.細胞形態觀察。細胞膜(mo)是(shi)(shi)每天必須觀察的(de)，看是(shi)(shi)否清(qing)晰，細胞的(de)死亡(wang)往往是(shi)(shi)從(cong)細胞膜(mo)的(de)破裂開始的(de)，早(zao)期的(de)表現(xian)就是(shi)(shi)細胞膜(mo)某(mou)一點(dian)出現(xian)欠(qian)完整或者毛發影。

2.細(xi)(xi)胞(bao)往往會有“抱(bao)團”現象，抱(bao)團生長或(huo)死亡，個人認(ren)為(wei)應(ying)該勤換(huan)液或(huo)傳(chuan)代，盡量避 免細(xi)(xi)胞(bao)抱(bao)團。

3.細(xi)胞生長迅速，強烈建議用(yong)較大的培養(yang)(yang)瓶養(yang)(yang)，用(yong)小(xiao)瓶養(yang)(yang)的話，換液不及時，很容易死 亡。細(xi)胞的生長速度一般為(wei)2天左右就需要傳代(dai)，并(bing)且一般為(wei)一傳三，或一傳四(si)。

4.培養(yang)液：1640|DMEM|MEM|IMDM|a-MEM培養(yang)液，1L一般加(jia)碳酸氫鈉2g，并加(jia)雙(shuang)抗，胎牛血清濃(nong)度*為(wei)12%，zui低不低于(yu)10%，有些細胞(bao)對胎牛血清高度依賴，比如WRO細胞(bao)，HT-22細胞(bao)，HA-VSMC細(xi)胞(bao)，NK-92細(xi)胞(bao)等。培養液PH應(ying)調為7.20-7.40之間。

5.防污(wu)染(ran)。L-02細(xi)胞生長(chang)迅速，較少發生污(wu)染(ran)，但常規(gui)措施應(ying)該做好。比如無(wu)菌操作，酒精 消(xiao)毒等，培養瓶(ping)口建(jian)議過火，包括瓶(ping)蓋(gai)，應(ying)過火4秒左右。

6.凍存。-20一小時(shi)，-80次夜，液(ye)(ye)氮長(chang)期(qi)保(bao)存。強烈建議液(ye)(ye)氮長(chang)期(qi)保(bao)存，盡量不(bu)要(yao)在-80長(chang)期(qi) 保(bao)存，死亡率很高。

7.復蘇。調節水浴箱溫度為42℃，并提前在(zai)試(shi)管內(nei)(nei)放置10倍培養(yang)液(ye)(ye)，使培養(yang)液(ye)(ye)溫度與室溫一(yi) 致。1分鐘內(nei)(nei)融化(hua)細胞(禁(jin)止搖晃凍存管)，移取至試(shi)管內(nei)(nei)，動作要輕，從試(shi)管管底開始慢慢上提 移液(ye)(ye)管，使細胞在(zai)培養(yang)液(ye)(ye)內(nei)(nei)分布均(jun)勻(yun)，離心，洗2次。
