| 应用 |
DAB（3,3′-二氨基联苯胺）在许多应用中用于显示过氧化物酶活性。在过氧化物酶反应中，DAB在过氧化物存在下用作氢供体。DAB氧化形成不溶性棕色终产物，可用于免疫组织学和免疫印迹染色。 |
| 产品介绍 |
DAB (3-3′ diaminobenzidine tetrachloride) is suitable for immunoblotting and immunohistochemical staining of nucleic acids and proteins. In HRP-based assays, the buffer oxidizes to a brown polymer in the presence of HRP and hydrogen peroxide that is insoluble in most organic solvents; sites of HRP activity on tissue sections and blots appear as brown-orange deposits, which can be intensified by treatment with salts of silver, copper, nickel, cobalt and osmium. |
