General description

Ammonium persulfate (APS) is a widely used reagent in biochemistry and molecular biology for the preparation of polyacrylamide gels. APS forms oxygen free radicals in aqueous solution by a base-catalyzed mechanism. The bases, most commonly used as catalysts, are tertiary amines such as TEMED (N,N,N′,N′-tetramethylethylenediamine) or DMAPN (3-dimethylaminopropionitrile). The free radicals will cause the polymerization of acrylamide and bis-acrylamide to form a gel matrix, which can be used for separating macromolecules by size. APS has also been utilized to study protein-protein interactions via photoinitiated crosslinking chemistry.

Application

Ammonium persulfate has been used for the preparation of polyacrylamide gels and acrylamide hydrogels.
Catalyst for acrylamide gel polymerization.

Analysis Note

Tested for use in acrylamide polymerization.
