描述
| 產(chǎn)品介紹 | 略有氨的氣味。 與水混溶，可混溶于乙醇、多數(shù)有機(jī)溶劑。 |
| 別名 | 四甲基乙二胺 ;四甲基乙撐二胺;N,N,N',N'-四甲基乙二胺;1,2-亞乙基二胺;1,2-雙(二甲基氨基)乙烷;TMEDA;TEMED;1,2-Bis(dimethylamino)ethane;TEMED;TMEDA |
| 生化機(jī)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%. |
| 應(yīng)用 | TEMED 是用于催化過硫酸銨或核黃素形成自由基的叔胺基。自由基將引起丙烯酰胺和 N,N'-亞甲基雙丙烯酰胺聚合形成可用于篩分大分子的凝膠基質(zhì)。 |
