SDS-PAGE protocol. Summary: SDS-PAGE stands for Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) and is a method used to separate proteins according to their size.Since different proteins with similar molecular weights may migrate differently due to their differences in secondary, tertiary or quaternary structure, SDS, an anionic detergent, is used in SDS-PAGE to reduce. Preparing Protein Samples for Electrophoresis. A polypeptide is a macromolecule consisting of a nonbranching sequence of amino acids, each connected to the next by a single peptide bond.
