Origen 二甲基亞砜DMSO及DMSO-DEX40供應 美國Origen DMSO 屬于非質(zhì)子極性溶劑,常用于化學反應、 PCR反應以及在細胞、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.依照標準凍存程序冷凍細胞,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、 cDNA文庫的擴增、 DNA測序、 DEAE-葡聚糖介導的細胞轉(zhuǎn)染、聚凝胺介導的 DNA轉(zhuǎn)染; (4)有相應的程序描述到用 DMSO回收膜過濾后的 DNA,用于接下來的 PCR擴增反應; (5)用于 DNA測序的毛細管電泳技術將 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。 產(chǎn)品基本信息: 1、CryoPur DMSO OriGen manufactures sterile filtered CryoPurTM 100% DMSO and CryoPur-DTM DMSO/Dextran.
