3,3′-二氨基联苯胺四盐酸盐水合物是一种常用于免疫组织化学和其他染色技术的显色剂，可在生物样品中可视化抗原或抗体的存在。DAB HCl 设计用作免疫组织学染料，以可视化观测细胞中的过氧化物酶活性。可通过分光光度计测量DAB氧化情况。 用途 3,3′-二氨基联苯胺四盐酸盐水合物适用于免疫组织学染色方案、蛋白质印迹和 FISH（荧光原位杂交）。DAB 用于研究早期白内障时的上皮细胞凋亡，以及常染色体显性遗传性多囊肾 (PKD) 的免疫组织化学方案。 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. A product used in HRP-based assays suitable for immunoblotting and immunohistochemical staining of nucleic acids and proteins.
