1,4-Dithiothreitol

别名: 1,4-二巯基苏糖醇, 1,4-二硫苏糖醇, DL-二硫苏糖醇, DTT, cleland′s 试剂, 二硫苏糖醇，1,4-, 克莱兰氏试剂

General description

1,4-dithiothreitol is commonly known as Cleland′s reagent. It confers protection to thiol groups and reduces disulfide bonds in peptides and proteins. It reduces disulfide bonds to sulfhydryl group and is commonly used in receptor studies, to determine the functional importance of disulfide bonds during receptor occupancy and functionality. It also maintains monothiols completely in the reduced state.

Application

1,4-二硫苏糖醇可用于：
• 蛋白和酶的分离、纯化和表征
• 酶活的测量（酶的重激活）
• 测定蛋白和酶中的二硫基团
• 扩增前的DNA提取
