細(xì)胞培養(yǎng)/凋亡時(shí),需要對(duì)其生長(zhǎng)和活性情況進(jìn)行觀察。由于細(xì)胞小而透明常采用細(xì)胞染色的方法觀察!今天小編整理了下常用染色方法,供大家參考! Hoechst 染色:Hoechst 可以穿過活細(xì)胞膜與細(xì)胞核結(jié)合(主要為凋亡活細(xì)胞)在紫外光下將核染色為藍(lán)色。
IP(碘化丙啶)染色:是一種可對(duì)DNA染色的細(xì)胞核染色試劑,常用于細(xì)胞凋亡檢測(cè)。碘化丙啶是一種核酸染料呈紅色,它不能透過完整的細(xì)胞膜,但凋亡中晚期的細(xì)胞和壞死細(xì)胞由于細(xì)胞通透性的增加,PI能夠透過細(xì)胞膜而使細(xì)胞核染紅,用PI 單一染色觀測(cè)培養(yǎng)細(xì)胞,只能表示細(xì)胞的壞死情況,而不是凋亡。
Annexin-V 染色:細(xì)胞凋亡早期,細(xì)胞膜標(biāo)志發(fā)生改變。其中磷脂酰絲氨酸外翻,Annexin-V在鈣離子存在的條件下與其高親和力特異性結(jié)合。這樣Annexin-V染色陽性,表示細(xì)胞處于早期凋亡狀態(tài)。Annexin-V結(jié)合不同的熒光抗體,就可以利用流式細(xì)胞儀、熒光顯微鏡以及共聚焦激光掃描顯微鏡檢查細(xì)胞凋亡的發(fā)生,Annexin-V用FITC標(biāo)記發(fā)綠色熒光;如果用PE標(biāo)記就發(fā)紅色熒光。 JC-1 染色:JC-1是一種陽離子染料,可以在線粒體內(nèi)聚集,低濃度時(shí)主要以單體存在,發(fā)射光以綠光為主;而在高濃度時(shí)則可以形成多聚體,發(fā)射光以紅光為主。線粒體本身存在一定的極性,其外膜為負(fù)極,內(nèi)膜為正極。電位差由鈣離子、鈉離子和氫離子流調(diào)控。當(dāng)線粒體狀態(tài)良好時(shí)對(duì)JC-1攝取量少,因而在線粒體內(nèi)主要以單體的形成存在綠光強(qiáng)度/紅光強(qiáng)度的比值較高。在線粒體發(fā)生去極化時(shí),線粒體內(nèi)JC-1的濃度較高,多以多聚體的形式存在,綠光強(qiáng)度/紅光強(qiáng)度的比值降低。 鈣黃綠素-AM(Calcein-AM): Calcein-AM 本身并不是熒光分子,但通過活細(xì)胞內(nèi)的酯酶作用Calcein-AM能脫去AM基,產(chǎn)生的Calcein 能發(fā)出強(qiáng)綠色熒光。因此Calcein-AM僅對(duì)活細(xì)胞染色。 臺(tái)盼藍(lán)染色:通常認(rèn)為細(xì)胞膜喪失完整性,細(xì)胞即可被認(rèn)為已經(jīng)死亡。臺(tái)盼藍(lán)是檢測(cè)細(xì)胞膜完整性常用的細(xì)胞染色試劑。健康的正常細(xì)胞能夠排斥臺(tái)盼藍(lán),而死亡的細(xì)胞,膜的完整性喪失,通透性增加,細(xì)胞可被臺(tái)盼藍(lán)染成藍(lán)色。從而實(shí)現(xiàn)對(duì)細(xì)胞存活率比較好的定量分析。
