"NEC8 epithelioid cells人畸胎瘤細(xì)胞系 細(xì)胞背景資料:睪丸胚胎性癌;男性 細(xì)胞形態(tài):上皮細(xì)胞樣 貼壁細(xì)胞消化傳代時(shí)通常采用兩種方法:一、加入胰酶等細(xì)胞脫落后,再加培養(yǎng)基中止胰酶作用,離心傳代;二、加入胰酶后,鏡下觀察待細(xì)胞始脫落時(shí),棄胰酶,加培養(yǎng)液分瓶。但前者太麻煩,而后者有可能對(duì)細(xì)胞施加胰酶選擇,因?yàn)榭偸琴N壁不牢的細(xì)胞先脫落,對(duì)腫瘤細(xì)胞來(lái)說(shuō),這部分細(xì)胞有可能是惡性程度較高的細(xì)胞亞群。一種簡(jiǎn)單的消化傳代方法。加入PBS洗去血清或加入胰酶先中和血清的作用(30s),棄之,再加入適量胰酶作用10s-40s(根據(jù)細(xì)胞消化的難易程度),棄之,這樣依賴殘余的胰酶就可將細(xì)胞消化單細(xì)胞。對(duì)于較難消化的細(xì)胞,可以用2%利多卡因消化5-8分鐘,然后再棄去,加培養(yǎng)基吹打也可以,對(duì)細(xì)胞的影響不大。不用PBS也不用Hanks洗,只要把舊培養(yǎng)液吸的干凈一點(diǎn),直接加酶消化應(yīng)該不會(huì)有什么問(wèn)題。棄培養(yǎng)液后,用0.04%的EDTA沖洗一次,再用1/4v的0.04%的EDTA室溫孵育5min,棄取大部分EDTA,加入與剩余EDTA等量的胰酶(預(yù)熱)總體積1/10v。消化到有細(xì)胞脫落。不過(guò)有人說(shuō)EDTA對(duì)細(xì)胞不好,有證據(jù)嗎?培養(yǎng)的BASMC:倒掉舊培養(yǎng)液加入少量胰酶沖一下,倒掉再加入0.125-0.25%胰酶約6-10滴或1ml(25ml bottle)消化再加入適量新培養(yǎng)基中和,并分瓶這種方法簡(jiǎn)單、省事;效果很好并且不損失細(xì)胞!

血清必須貯存于–20~-70℃,若存放于4℃,請(qǐng)勿超過(guò)一個(gè)月。如果一次無(wú)法用完一瓶,可將40~45ml分裝于無(wú)菌50ml離心管中,由于血清結(jié)凍時(shí)體積會(huì)增加約10%,必須預(yù)留此膨脹體積之空間,否則易發(fā)生污染或容器凍裂之情形。一般廠商提供之血清為無(wú)菌,不需再無(wú)菌過(guò)濾。若發(fā)現(xiàn)血清有許多懸浮物,則可將血清加入培養(yǎng)基內(nèi)一起過(guò)濾,勿直接過(guò)濾血清。瓶裝(500ml)血清解凍步驟(逐步解凍法):-20℃或–70℃至4℃冰箱溶解一天,至室溫下全溶后再分裝,一般以50ml無(wú)菌離心管可分裝40~45ml。在溶解過(guò)程中須規(guī)則搖晃均勻(小心勿造成氣泡),使溫度與成分均一,減少沈淀的發(fā)生。勿直接由–20℃直接至37℃解凍,因溫度改變太大,容易造成蛋白質(zhì)凝結(jié)而發(fā)生沈淀。勿將血清置于37℃太久,若在37℃放置太久,血清會(huì)變得混濁,同時(shí)血清中許多較不穩(wěn)定之成份亦會(huì)因此受到破壞,而影響血清之品質(zhì)。血清凝絮物:發(fā)生之原因有許多種,但普遍之原因是血清中之脂蛋白(lipoprotein)
