  • Introduction to Polyacrylamide Gels | LSR | Bio-Rad

    Polyacrylamide gels are made by chemical polymerization of a mixture of acrylamide and bisacrylamide (a cross-linker) in the presence of a catalyst and an initiator of the polymerization reaction. The porosity of the gel is determined by the relative concentration of acrylamide to cross-linker and by the total percentage of monomers.
