應用

还原剂
β-巯基乙醇或2-巯基乙醇已用于:
  • 作为Roswell Park Memorial Institute (RPMI)-1640培养基的一种补充剂用于DT40细胞(鸡B细胞系)的培养
  • 裂解NuLi-1(Normal Lung, University of Iowa-1)细胞
  • 小鼠胚胎干细胞的胰蛋白酶消化
BME 适用于在聚丙烯酰胺凝胶电泳前还原蛋白质二硫键,通常用于 SDS-PAGE 的样品缓冲液,浓度为 5%。 切割分子间(亚基之间)二硫键允许蛋白质的亚基在 SDS-PAGE 上独立分离。 切割分子内(亚基内)二硫键可使亚基完全变性,从而使每个肽根据其链长迁移,而不受二级结构的影响。
