WebbIn standard SDS-PAGE, the charge-shift molecule is SDS. The SDS denatures proteins and binds to proteins conferring a net negative charge allowing the proteins to migrate in one direction towards the anode. The SDS is present in the sample buffer and running buffer. WebbSDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis, describes a collection of related techniques to separate proteins according to their electrophoretic mobility (a function of the molecular weight of a polypeptide chain) while in the denatured (unfolded) state. In most proteins, the binding of SDS to the polypeptide chain imparts …
