Analysis Note Tested for use in acrylamide polymerization.
Application Ammonium persulfate forms oxygen free radicals in aqueous solution by a base-catalyzed mechanism1. The bases most commonly used as catalysts are tertiary amines such as N,N,N′,N′-tetramethylethylenediamine (TEMED) or 3-dimethylaminopropionitrile (DMAPN). 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.
  Catalyst for acrylamide gel polymerization.
