WebSDS is a detergent that contains a long aliphatic chain and a sulfate group. This detergent interacts with denatured proteins to form a strongly negatively charged complex (the negative charge arising from the SO 42− groups of SDS). The proteins are first denatured by heat and then the SDS is added in large excess.
