Alcian Blue pyridine variant（Cat No.:M027409）is a synthetic dye widely used in histology and cell biology for staining acidic polysaccharides such as glycosaminoglycans and mucins. The pyridine variant enhances the dye’s ability to bind to negatively charged molecules, making it particularly effective for identifying and visualizing structures in tissues that are rich in sulfated and carboxylated mucopolysaccharides. Commonly used in medical diagnostics and research, it is crucial for studying cartilage, connective tissues, and tumor specimens. This variant is valued for its stability and high contrast in staining applications.
