一般描述

特点及优势:

  • 适于分子应用
  • 无核酸酶DMSO
  • 不含DNase、RNase、蛋白酶和磷酸酶
  • 分子生物学级DMSO

二甲基亚砜(DMSO)是一种对有机和无机化学品具有出色溶剂性质的高极性有机试剂。
该产品为分子生物学级,适用于分子生物学应用,对其中核酸酶和蛋白酶的存在也进行了分析。

应用

DMSO(二甲基亚砜)是一种在有机化学和分子生物学中具有诸多应用的高度极性、非质子有机溶剂。DMSO通常用于

  • 聚合酶链式反应 (PCR)
  • cDNA文库扩增
  • DNA测序
  • poly(A)+ RNA筛选的上柱缓冲液
  • 感受态大肠杆菌转化缓冲液
  • 转染方案。

二甲基亚砜已用于-

  • 用作芯片点样应用中的寡核苷酸溶剂[1]
  • 用作miRNA芯片分析和实时荧光定量PCR (qRT-PCR)中的溶剂
  • 在MTT(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴化物)测定的细胞裂解液
  • 制备MMP(线粒体膜电位)细胞荧光评估过程所用的储备溶液
  • 用作储存人类和动物细胞系和噬菌体λ的冷冻保护剂。
制备无菌过滤DMSO溶液时,建议使用PTFE或尼龙膜。不建议使用醋酸纤维素膜。

特点和优势

该产品不含DNase、RNase、磷酸酶和蛋白酶。

注意

在室温下容易过冷并缓慢重融。 固化产品可以通过加热至室温来重新液化,而不会损害产品。
