Polyacrylamide

Polyacrylamide is a three-dimensional mesh formed by the copolymerization of an activated monomer acrylamide and a cross-linking agent methylenebisacrylamide, initiated by the presence of sulphate free radicals. A polyacrylamide gel is used in SDS Polyacrylamide-Gel Elctrophoresis (SDS-PAGE), because it is chemically inert so there is no chemical interference with the proteins to be separated, is readily formed by its monomers and the pore size of the gel can be adjusted to separate proteins of different sizes by retarding the proteins of interest ^[1] ^[2].
