The Toluidine Blue O (CI 52040) Analytical Grade by Dinâmica, available at LojaLab, is a basic cationic thiazine dye used in histology, cytology, microbiology and microscopy. Its best-known property is metachromasia: structures containing closely spaced anionic groups such as sulfates and phosphates may display a color different from the dyes orthocromatic blue. This response helps reveal mast cells, cartilage matrix, acidic mucopolysaccharides and Nissl substance.
Characteristics
- Basic cationic dye from the thiazine class
- Colour Index C.I. 52040 with intense blue color
- Produces metachromasia in structures rich in anionic groups
