Toluidine Blue

Catalog No.: B21300
Basic Dye
Toluidine Blue, an alkaline quinonimine dye, demonstrates a strong affinity for acidic tissue components, effectively staining nuclei blue and polysaccharides purple. This reagent exhibits heterostaining properties, enabling visualization of mast cells, mucins, and chondrocytes. Additionally, Toluidine Blue is employed in the histological analysis of plant tissues and is utilized as a diagnostic aid for identifying malignant lesions, including cancerous tissues. Its versatile staining capabilities make it a valuable tool in both medical and botanical research applications.
