    What is Polyacrylamide Gel Electrophoresis (PAGE)?

    Principles of PageSDS-PAGE ProtocolReferencesFurther ReadingIn PAGE, an anionic detergent called sodium dodecyl sulfate (SDS) is used to bind to proteins and give them a negative charge. Proteins are then separated electrophoretically according to their size using a gel matrix made of polyacrylamide in an electric field.Polyacrylamide is produced as a result of the polymerization reaction between acrylamide and N,N'-methylene-bis-acrylamide (BIS) using a catalyst.
