DAB HCl is designed as an immunohistology stain to visualise peroxidase activity in cells. DAB oxidation can be measured using a spectrophotometer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e3,3'-Diaminobenzidine tetrahydrochloride hydrate is suitable for immunohistology staining procedures, western blotting, and FISH (fluorescence in situ hybridisation). DAB is used in studying epithelial cell apoptosis in the event of early cataracts, and immunohistochemistry protocols of autosomal dominant polycystic kidney disease (PKD).\u003c\/p\u003e\u003cp\u003eIn the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide.
