Ammonium Persulphate (APS) (MB03403)

Description: Used as a catalyst for acrylamide gel polymerization. Ammonium persulfate forms oxygen free radicals in aqueous solution by a base-catalyzed mechanism. The bases most commonly used as catalysts are tertiary amines such as N,N,N′,N′-tetramethylethylenediamine (TEMED). The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix, which can be used for separating macromolecules by size.
