Description
| 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. |
