Description

General description

N,N′-Methylenebisacrylamide is commonly called as bis. It is used as a cross-linking agent in the preparation of polyacrylamide gels consisting of chains of acrylamide monomers. The concentration of N,N′-methylenebisacrylamide and acrylamide determines the pore size of the gel. The higher concentration of bis forms rigid gels with smaller pores due to more cross-linking leading to polymerization and vice versa.

Application

N,N′-Methylenebisacrylamide has been used:

• as a crosslinker in the monomer solution to prepare N,N-dimethyl acrylamide (DMAAm)-based cryogel and acrylamide (AAm)-based cryogel matrix
• as a crosslinker to prepare tough hydrogel network
• in the preparation of acrylamide-bisacrylamide stock solution for the preparation of polyacrylamide gel

To be mixed with acrylamide for making polyacrylamide gels for use in protein and nucleic acid electrophoresis.
