Toluidine Blue (purity 36%)（Cat No.:I042811）is a synthetic dye commonly used in histology, microscopy, and staining procedures. It is a basic thiazine dye that binds to acidic tissue components such as nucleic acids, making it useful for staining cell nuclei, cytoplasm, and tissues in biological samples. The 36% purity version is typically employed in applications requiring a more concentrated solution or specific staining characteristics. Toluidine Blue is particularly useful for identifying cellular structures, detecting mucopolysaccharides, and assessing tissue morphology, especially in research related to cancer, pathology, and histological studies.
