Description

General description

SDS (sodium dodecyl sulfate) is a wetting agent and an anionic detergent which functions efficiently in both alkaline and acidic solutions. It is generally used for the solubilization of lipids and proteins. It also functions as a potent protein denaturant. SDS, volume-wise, is one of the most commonly used synthetic surfactants.

Application

Anionic detergent
