產(chǎn)品簡(jiǎn)介
DMSO用于細(xì)胞冷凍培養(yǎng)基內(nèi),可以保護(hù)細(xì)胞免受冰晶引起的機(jī)械性損傷。
DMSO-DEX40用于血液凍存。

Origen 二甲基亞砜DMSODMSO-DEX40供應(yīng)

美國(guó)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(xì)胞、組織和器官的保存中用作玻璃化低溫冷凍防護(hù)劑。 DMSO用于細(xì)胞冷凍培養(yǎng)基內(nèi),可以保護(hù)細(xì)胞免受冰晶引起的機(jī)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(xì)胞株,胚胎干細(xì)胞( ESC)和造血干細(xì)胞的冷凍保藏。另外常常與 BSAFBS混合使用。

    途:

1 DMSO廣泛應(yīng)用在人、動(dòng)物細(xì)胞株及細(xì)菌噬菌體λ的低溫防護(hù)中,制備 DMSO溶液用來(lái)冷凍細(xì)胞的步驟如下:

A.配制冷凍培養(yǎng)基:含有細(xì)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(xì)胞;(細(xì)胞處于對(duì)數(shù)增長(zhǎng)期)

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

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

E.平均分配細(xì)胞,裝入凍存管內(nèi);

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

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

3)有文獻(xiàn)報(bào)道 DMSO作為緩沖液的成分,用于以下的實(shí)驗(yàn):PolyA+RNA 的純化, E. coli感受態(tài)細(xì)胞轉(zhuǎn)化、 PCR反應(yīng)、 cDNA文庫(kù)的擴(kuò)增、 DNA測(cè)序、 DEAE-葡聚糖介導(dǎo)的細(xì)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(guò)濾后的 DNA,用于接下來(lái)的 PCR擴(kuò)增反應(yīng);

5)用于 DNA測(cè)序的毛細(xì)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(bào)道不同濃度的 DMSO與寡核苷酸的熔點(diǎn)溫度關(guān)系;

7)有研究描述利用 DMSO提高雜交瘤細(xì)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(xì)胞。

8)文獻(xiàn)報(bào)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(xiàn)報(bào)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

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

注意事項(xiàng):

    僅用于實(shí)驗(yàn)室,不可用于藥品、家居和其他用處 。

使用說(shuō)明:

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

儲(chǔ)存 /穩(wěn)定性:

DMSO 容易過(guò)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(duì)其本身無(wú)損害。屬于熱穩(wěn)定化合物,在高達(dá) 100℃的酸、堿及中性溶液中保持穩(wěn)定。溫度接近其沸點(diǎn)(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 nylon膜,盡量不用醋酸纖維素膜。
