描述
| 产品介绍 | 略有氨的气味。 与水混溶，可混溶于乙醇、多数有机溶剂。 |
| 别名 | 四甲基乙二胺 ;四甲基乙撑二胺;N,N,N',N'-四甲基乙二胺;1,2-亚乙基二胺;1,2-双(二甲基氨基)乙烷;TMEDA;TEMED;1,2-Bis(dimethylamino)ethane;TEMED;TMEDA |
| 生化机理 | TEMED (N,N,N′,N′-Tetramethylethylenediamine) is a free radical stabilizer used as a catalyst with APS (Ammonium persulfate) to promote polymerization of Acrylamide/bis-Acrylamide gels. Also employed as a ligand for metal ions as it forms stable complexes with many metal halides, e.g. zinc chloride and copper(I) iodide, giving complexes that are soluble in organic solvents. In such complexes, TEMED serves as a bidentate ligand. Ready-to-use acrylamide solutions are available for your convenience: Acrylamide Solution, 40% and N,N′-Methylenebis-Acrylamide,2%. |
| 应用 | TEMED 是用于催化过硫酸铵或核黄素形成自由基的叔胺基。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可用于筛分大分子的凝胶基质。 |
