Fast Red ITR（Cat No.:I043241）is a diazonium salt used in histochemistry and immunohistochemistry for staining applications. It is a synthetic dye that reacts with alkaline phosphatase to produce a red-colored precipitate, making it useful for visualizing tissue samples or detecting specific antigens in cells. Fast Red ITR is commonly employed in research to study cellular structures, enzyme activity, and protein localization. Its application is widespread in areas such as molecular biology, pathology, and diagnostics. The bright red coloration provides high contrast, allowing for precise and detailed imaging in tissue analysis.
