Description

Brilliant Cresyl Blue is a synthetic phenoxazine dye widely recognized for its metachromatic staining properties. This compound is a vital biological stain, particularly valued for its selective affinity for specific cellular components like RNA and certain granules. It serves as an essential tool for researchers and quality control laboratories in life sciences, histology, and diagnostic applications. The product is supplied as a high-purity chemical suitable for demanding analytical and research procedures.

Application

• Biological Staining: Used as a metachromatic stain for blood cells, nerve tissue, and cartilage in histological and cytological preparations.
• Microscopy & Diagnostics: Employed in the staining of reticulocytes (reticulocyte count) and for highlighting specific granules in mast cells and basophils.
• Vital Staining: Applied in supravital staining techniques to differentiate living cells in suspension.
• Research Reagent: Serves as a key reagent in neuroscience research for staining Nissl substance and in studies of lysosomal function.
• Industrial Dye: Functions as a colorant in specialized applications, including inks and pigments, where its specific hue is required.
• Quality Control: Used as a standard or reference material in pharmaceutical and diagnostic kit manufacturing.
