Origen 二甲基亞砜DMSO及DMSO-DEX40供應(yīng)

美國Origen

    DMSO 屬于非質(zhì)子極性溶劑，常用于化學(xué)反應(yīng)、 PCR反應(yīng)以及在細胞、組織和器官的保存中用作玻璃化低溫冷凍防護劑。 DMSO用于細胞冷凍培養(yǎng)基內(nèi)，可以保護細胞免受冰晶引起的機械性損傷。它也可以用于主培養(yǎng)、亞培養(yǎng)、重組異倍體、雜交瘤等系列細胞株，胚胎干細胞（ ESC）和造血干細胞的冷凍保藏。另外常常與 BSA或FBS混合使用。

用    途：

（1） DMSO廣泛應(yīng)用在人、動物細胞株及細菌噬菌體λ的低溫防護中，制備 DMSO溶液用來冷凍細胞的步驟如下：

A.配制冷凍培養(yǎng)基：含有細胞培養(yǎng)用培養(yǎng)基、 10-20% 血清和 5-10% DMSO；

B.用胰酶或其他合適的方法消化貼壁細胞；（細胞處于對數(shù)增長期）

C.低速離心（4℃，250×g, 10min）收集細胞，吸去培養(yǎng)基；

D.用冷凍培養(yǎng)基懸浮細胞，使細胞密度為 10⁶ -10⁷ cells/ml；

E.平均分配細胞，裝入凍存管內(nèi)；

F.依照標(biāo)準(zhǔn)凍存程序冷凍細胞，凍存在 -70℃或更低的溫度內(nèi)；

（2）細胞融合時，40-50% PEG 溶液內(nèi)加入10% DMSO；

（3）有文獻報道 DMSO作為緩沖液的成分，用于以下的實驗：Poly（A+）RNA 的純化， E. coli感受態(tài)細胞轉(zhuǎn)化、 PCR反應(yīng)、 cDNA文庫的擴增、 DNA測序、 DEAE-葡聚糖介導(dǎo)的細胞轉(zhuǎn)染、聚凝胺介導(dǎo)的 DNA轉(zhuǎn)染；

（4）有相應(yīng)的程序描述到用 DMSO回收膜過濾后的 DNA，用于接下來的 PCR擴增反應(yīng)；

（5）用于 DNA測序的毛細管電泳技術(shù)將 5% DMSO (v/w)混入 2 M尿素中，如果需要可以調(diào)整 DMSO濃度到100%。

（6）有研究報道不同濃度的 DMSO與寡核苷酸的熔點溫度關(guān)系；

（7）有研究描述利用 DMSO提高雜交瘤細胞中單克隆抗體的產(chǎn)量； 調(diào)查發(fā)現(xiàn)低溫冷凍前用含有 DMSO的培養(yǎng)基高溫培養(yǎng)雜交瘤細胞。

（8）文獻報道利用 DMSO修飾蛋白中的磷酸絲氨酸和磷酸蘇氨酸殘基用作磷酸化狀態(tài)的質(zhì)譜分析（ MS）；

（9）文獻報道水和 DMSO中的亮脯利特（Leuprolide）降解作用；

互溶性：

? *互溶： LDPE, HDPE，聚丙烯 , PPCO, 聚甲基戊烯，尼龍， teflon FEP

? 中度互溶：聚苯乙烯， ECTFE/ETFE

? 不 互 溶：聚砜 ,， flexible and rigid PVC tubing，聚碳酸脂

注意事項：

    僅用于實驗室，不可用于藥品、家居和其他用處 。

使用說明：

    DMSO 易于水混合（ 1 ml DMSO + 1 ml H2O）形成清澈、無色的溶液。易吸潮，免暴露在潮濕環(huán)境。

儲存 /穩(wěn)定性：

DMSO 容易過冷并且室溫下緩慢融化，收到的產(chǎn)品應(yīng)為固體并非液體狀態(tài)。固化的 DMSO放在室溫下可以再次液化，對其本身無損害。屬于熱穩(wěn)定化合物，在高達 100℃的酸、堿及中性溶液中保持穩(wěn)定。溫度接近其沸點（189℃），在堿性和中性溶液中仍保持穩(wěn)定。 150℃加熱 24h，其純度損失小于0.1%。

要制備濾膜除菌的 DMSO溶液，推薦使用 teflon或 nylon膜，盡量不用醋酸纖維素膜。
