Sodium lauryl sulfate is a commonly used ionic detergent that disintegrates cell membranes, binds to the hydrophobic portion of membrane proteins and separates them from membranes. High concentrations of SDS can also destroy ionic bonds and hydrogen in proteins. Non-covalent bonds such as bonds, even changing the conformation of proteins. This feature is commonly used in SDS gel electrophoresis for protein component analysis.
