Immunohistochemistry (IHC) is a cornerstone technique in biological research and diagnostics, enabling the visualization of specific proteins and antigens within tissue samples. At the heart of many successful IHC protocols lies a reliable chromogenic substrate, and 3,3'-Diaminobenzidine Tetrahydrochloride (CAS 7411-49-6) stands out as a premier choice for many scientists and laboratories. As a leading manufacturer and supplier of high-quality fine chemicals in China, we understand the critical importance of purity and consistency for these sensitive applications.

Why Choose 3,3'-Diaminobenzidine Tetrahydrochloride for Your IHC Needs?

The primary advantage of using 3,3'-Diaminobenzidine Tetrahydrochloride, often abbreviated as DAB, is its performance as a substrate for horseradish peroxidase (HRP). When HRP is conjugated to primary or secondary antibodies and exposed to DAB in the presence of hydrogen peroxide, a localized oxidative reaction occurs. This reaction precipitates a distinct, insoluble brown polymer precisely at the site of antigen-antibody binding. This characteristic makes it an invaluable tool for researchers aiming to accurately pinpoint protein expression and localization within cells and tissues. Many scientists worldwide search for 'buy 3,3'-diaminobenzidine tetrahydrochloride' to ensure they are using a high-grade product.

Applications Beyond Basic Staining

While its role in IHC is paramount, the utility of CAS 7411-49-6 extends to other critical biological staining techniques. It is also frequently employed in In-Situ Hybridization (ISH), where it serves as a chromogen to detect specific nucleic acid sequences. This broad applicability underscores its importance as a versatile chemical intermediate in life science research. Its stability and water-soluble nature simplify its handling and integration into various experimental workflows, making it a preferred choice for laboratories that prioritize efficiency and reproducible results.
