Fast Blue B salt（Cat No.:M059058） is a diazo dye used primarily in biological staining for microscopy. This compound serves as a coupling agent in colorimetric tests to detect enzymatic activity, particularly for identifying esterase and phosphatase activities in tissue sections. When used in histochemical staining, Fast Blue B reacts with specific enzyme substrates to produce vivid blue-colored precipitates, allowing for the detailed visualization of cellular components under a microscope. Its effectiveness in differentiating cellular structures makes it a valuable tool in both clinical diagnostics and research settings.
