CAL-51細胞CAL-51細胞培養(yang)步驟(zou):
1)復蘇細(xi)(xi)胞(bao):將(jiang)含(han)有(you)1mL細(xi)(xi)胞(bao)懸(xuan)液(ye)的凍(dong)存管在(zai)(zai)37℃水浴(yu)中迅(xun)速(su)搖晃(huang)解凍(dong),加(jia)入(ru)5mL培(pei)養(yang)(yang)(yang)基混(hun)合均勻。在(zai)(zai)1000RPM條件下離心5分鐘,棄(qi)去上清液(ye),補(bu)加(jia)4-6mL*培(pei)養(yang)(yang)(yang)基后(hou)吹勻。然后(hou)將(jiang)所有(you)細(xi)(xi)胞(bao)懸(xuan)液(ye)加(jia)入(ru)培(pei)養(yang)(yang)(yang)瓶(ping)中培(pei)養(yang)(yang)(yang)過夜(或將(jiang)細(xi)(xi)胞(bao)懸(xuan)液(ye)加(jia)入(ru)6cm皿中),培(pei)養(yang)(yang)(yang)過夜。第二天換液(ye)并檢查細(xi)(xi)胞(bao)密(mi)度(du)。
2)細胞傳代(dai):如果(guo)細胞密度達80%-90%,即可(ke)進(jin)行(xing)傳代(dai)培養。
1、對于(yu)貼壁細(xi)胞,傳代可參考以下(xia)方法:
1. 棄(qi)去培養上清,用不含鈣、鎂離(li)子的(de)PBS潤洗細胞1-2次。
2. 加1-2ml消(xiao)(xiao)化(hua)液(ye)(0.25%Trypsin-0.53mM EDTA)于(yu)培(pei)(pei)(pei)養瓶中,置于(yu)37℃培(pei)(pei)(pei)養箱中消(xiao)(xiao)化(hua)1-2min,然(ran)后在(zai)顯(xian)微(wei)鏡下(xia)觀察細胞(bao)消(xiao)(xiao)化(hua)情況,若細胞(bao)大部(bu)分變圓(yuan)并脫落,迅(xun)速拿回(hui)操作臺,輕敲幾下(xia)培(pei)(pei)(pei)養瓶后加5ml以(yi)上含10%血(xue)清的*培(pei)(pei)(pei)養基終止消(xiao)(xiao)化(hua)。
3.輕(qing)輕(qing)吹打細(xi)胞,*脫落后吸出,在1000RPM條(tiao)件下離心8-10分鐘,棄去上清液(ye)(ye),補加1-2mL培養液(ye)(ye)后吹勻。
4. 按(an)5-6ml/瓶補加(jia)培養液,將細胞(bao)懸(xuan)液按(an)1:2到1:5的比例分到新的含5-6 ml培養液的新皿中或(huo)者瓶中。
PS:若客戶收到2ml小(xiao)管細(xi)胞,收到細(xi)胞后(hou),用(yong)75%酒精(jing)噴(pen)灑(sa)整個(ge)管子消毒后(hou)放到超(chao)(chao)凈臺或(huo)(huo)安(an)全柜內,嚴(yan)格無菌操作;將(jiang)小(xiao)管細(xi)胞轉(zhuan)移至T25培(pei)養(yang)瓶或(huo)(huo)6cm培(pei)養(yang)皿(min),加入(ru)5ml左右*培(pei)養(yang)基混勻,放入(ru)培(pei)養(yang)箱過(guo)夜(ye)培(pei)養(yang)后(hou)查看細(xi)胞密度(du)(du):若密度(du)(du)未超(chao)(chao)過(guo)80%,換液繼(ji)續培(pei)養(yang),視(shi)情況(kuang)傳代或(huo)(huo)者凍(dong)存(cun)。若密度(du)(du)超(chao)(chao)過(guo)80%,可(ke)直接進行傳代(方法同(tong)上(shang))。
2、對于懸浮細(xi)胞(bao),傳代可(ke)參考(kao)以下方法:
方法(fa)一:收集(ji)細胞(bao),1000RPM條件下離心(xin)8-10分鐘,棄去上清液,補加1-2mL培(pei)養(yang)液后吹(chui)勻,將(jiang)細胞(bao)懸液按1:2到(dao)1:5的(de)(de)比例(li)分到(dao)新的(de)(de)含8ml培(pei)養(yang)基的(de)(de)新皿中或者(zhe)瓶中。
方(fang)法二(er):可選擇半數換液(ye)(ye)方(fang)式,棄去半數培養基后,將(jiang)剩余(yu)細胞懸起,將(jiang)細胞懸液(ye)(ye)按1:2到1:3的(de)比例分到新的(de)含8ml培養基的(de)新皿中(zhong)或者瓶中(zhong)。
3)細(xi)(xi)胞凍(dong)存:待細(xi)(xi)胞生(sheng)長狀態良好時(shi),可進行(xing)細(xi)(xi)胞凍(dong)存。貼(tie)壁細(xi)(xi)胞凍(dong)存時(shi),棄去(qu)(qu)培(pei)養基后(hou)加入(ru)少(shao)量胰(yi)酶,細(xi)(xi)胞變(bian)圓(yuan)脫落后(hou),進行(xing)離(li)心(xin)收集,1000RPM條件下離(li)心(xin)8-10分鐘,去(qu)(qu)除上清,按(an)凍(dong)存數量加入(ru)血清及DMSO,凍(dong)存比(bi)例(li)為90%FBS+10%DMSO。
PS:若客戶收(shou)到(dao)2ml小(xiao)管(guan)細(xi)(xi)(xi)胞(bao),收(shou)到(dao)細(xi)(xi)(xi)胞(bao)后(hou),用75%酒精噴灑整個管(guan)子消毒后(hou)放到(dao)超(chao)凈臺或安(an)全柜內(nei),嚴(yan)格無菌操(cao)作;將小(xiao)管(guan)細(xi)(xi)(xi)胞(bao)轉移(yi)至T25培(pei)養(yang)瓶或6cm培(pei)養(yang)皿,加入5ml左右*培(pei)養(yang)基混勻,放入培(pei)養(yang)箱過(guo)夜(ye)培(pei)養(yang)后(hou)查看(kan)細(xi)(xi)(xi)胞(bao)密度:若密度未(wei)超(chao)過(guo)80%,換液繼續培(pei)養(yang),視情況傳代(dai)(dai)或者凍存。若密度超(chao)過(guo)80%,可直接進行傳代(dai)(dai)(方法同上)。
