DETAILS

Description (English)
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.
Packaging
25, 100 g in poly bottle
Description (简体中文)
Analysis Note
经过测试可用于丙烯酰胺聚合反应。
Application
丙烯酰胺凝胶聚合催化剂。
过硫酸铵通过碱催化机理在水溶液中形成氧自由基1。通常用作催化剂的碱为叔胺类物质,例如 N,N,N′,N′-四甲基乙二胺 (TEMED) 或 3-二甲氨基丙腈 (DMAPN)。自由基将引起丙烯酰胺和 N,N'-亚甲基双丙烯酰胺聚合形成凝胶基质,该凝胶基质可用于按大小分离大分子。
包装
25, 100 g in poly bottle
