一般描述

Sodium dodecyl sulfate (SDS) is an amphipathic detergent commonly used for denaturing proteins. SDS has a long-chain aliphatic group, with negatively charged sulfate groups that coat the surface of proteins, causing them to lose their quaternary structure.

应用

十二烷基硫酸钠已用于：
  • 染色体免疫沉淀
  • SDS-聚丙烯酰胺凝胶电泳（SDS-PAGE）
  • 作为用于免疫印迹的放射免疫沉淀检测缓冲液的一种组分
阴离子洗涤剂

分析说明

针对用于变性聚丙烯酰胺凝胶电泳进行了测试。
