    2014-9-7 · Denaturing polyacrylamide gel electrophoresis using sodiumdodecyl sulphate (SDS-PAGE) is the most common modeof electrophoresis used in assessing the pharmaceuticalquality of protein products and will be the focus of theexample method. Typically, analytical electrophoresisof proteins is carried out in polyacrylamide gels underconditions that ensure dissociation of the proteins intotheir individual polypeptide subunits and that minimiseaggregation. Most commonly, the strongly anionic detergentsodium dodecyl sulphate (SDS) is used in combination withheat to dissociate the proteins before they are loaded onthe gel. The denatured polypeptides bind to SDS, becomenegatively charged and exhibit a consistent charge-to-massratio regardless of protein type. Because the amount ofSDS bound is almost always proportional to the molecularmass of the polypeptide and is independent of its sequence,SDS-polypeptide complexes migrate through polyacrylamidegels …
