一般描述

十二烷基硫酸钠(SDS)是一种阴离子表面活性剂，又称月桂基硫酸盐。
Sodium dodecyl sulfate (SDS), or sodium lauryl sulfate, is widely recognized as an anionic surfactant within the organosulfate class of organic compounds. Its effectiveness as a detergent spans both ionic and anionic conditions. SDS plays a critical role as a protein denaturant, facilitating the solubilization and denaturation of proteins in procedures like protein extraction and SDS-PAGE. Its significance in the electrophoretic separation of proteins and lipids establishes its indispensability for the examination of these molecules in diverse biological experiments. In conclusion, Sodium dodecyl sulfate proves to be an indispensable element in the exploration of biological molecules within the realms of biochemical and cell biology research.

应用
