Description

Application

Anionic detergent

SDS may be used:
• in peptide mapping and protein analysis by gel electrophoresis.
• to utilize in designing formulations and its effect on adsorption and micellization parameters.
• in measuring protein-SDS complexes and SDS solution in guanidine hydrochloride using gel chromatography.
• in seperating protein subunits dissociated with SDS using Hydroxylapatite chromatography.
