 背景知識(shí):
細(xì)胞凍存是細(xì)胞保存的主要方法之一。利用凍存技術(shù)將細(xì)胞置于-196℃液氮中低溫保存,可以使細(xì)胞暫時(shí)脫離生長(zhǎng)狀態(tài)而將其細(xì)胞特性保存起來,這樣在需要的時(shí)候再?gòu)?fù)蘇細(xì)胞用于實(shí)驗(yàn)。而且適度地保存一定量的細(xì)胞,可以防止因正在培養(yǎng)的細(xì)胞被污染或其他意外事件而使細(xì)胞丟種,起到了細(xì)胞保種的作用。除此之外,還可以利用細(xì)胞凍存的形式來購(gòu)買、寄贈(zèng)、交換和運(yùn)送某些細(xì)胞。 細(xì)胞凍存時(shí)向培養(yǎng)基中加入保護(hù)劑--終濃度5%.15%的甘油或二甲基亞砜(DMSO),可使溶液冰點(diǎn)降低,加之在緩慢凍結(jié)條件下,細(xì)胞內(nèi)水分透出,減少了冰晶形成,從而避免細(xì)胞損傷。 采用"慢凍快融"的方法能較好地保證細(xì)胞存活。標(biāo)準(zhǔn)冷凍速度開始為-1 到 -2℃/min,當(dāng)溫度低于-25℃時(shí)可加速,到-80℃之后可直接投入液氮內(nèi)(-196℃)。
二甲基亞砜(DMSO)是一種含硫有機(jī)化合物,常溫下為無色無味的透明液體,是一種吸濕性的可燃液體,具有高極性、高沸點(diǎn)、熱穩(wěn)定性好、非質(zhì)子、與水混溶的特性,能溶于乙醇、丙醇、苯等大多數(shù)有機(jī)物,被譽(yù)為“萬能溶劑”。二甲基亞砜是一種重要的滲透性細(xì)胞保護(hù)劑。在深低溫(零下200度)保存細(xì)胞時(shí)凍存過程中,為防止細(xì)胞內(nèi)液冰晶形成、滲透壓改變、細(xì)胞結(jié)構(gòu)紊亂等導(dǎo)致的損傷,有必要使用含有DMSO冷凍保護(hù)劑。DMSO能夠快速穿透細(xì)胞膜進(jìn)入細(xì)胞中,降低冰點(diǎn),延緩凍存過程,同時(shí)提高細(xì)胞內(nèi)離子濃度,減少細(xì)胞內(nèi)冰晶的形成,從而減少細(xì)胞損傷。深低溫時(shí)二甲基亞砜的細(xì)胞毒性受到抑制。復(fù)蘇時(shí)動(dòng)作要快,盡快洗掉二甲基亞砜,否則會(huì)造成對(duì)細(xì)胞嚴(yán)重的毒性。二甲基亞砜(DMSO)是目前的細(xì)胞凍存保護(hù)劑,但也是一種細(xì)胞毒性很大的化學(xué)試劑。研究結(jié)果表明,培養(yǎng)液中DMSO濃度為10%時(shí),細(xì)胞生長(zhǎng)抑制率近100%;1%濃度時(shí)抑制率為35%,即使是0.04%的濃度,DMSO對(duì)細(xì)胞的生長(zhǎng)也有不利的影響。
右旋糖酐系蔗糖是經(jīng)腸膜狀明串珠菌-1226(Leuconostoc mesenteroides)發(fā)酵合成的一種高分子葡萄糖聚合物,右旋糖酐-40(Dextran-40)別稱低分子右旋糖酐,右旋糖酐40的重均分子量(Mw)應(yīng)為32000~42000。右旋糖酐-40可以維持滲透壓和 PiH , 提供適宜細(xì)胞存活的介質(zhì)環(huán)境。
OriGen公司研發(fā)的二甲亞砜(DMSO)在高級(jí)別DMSO的精制領(lǐng)域中處于地位,其細(xì)胞凍存級(jí)產(chǎn)品在市場(chǎng)上擁有較高的占有率,經(jīng)過十多年的客戶檢驗(yàn)與使用,質(zhì)量過硬。
