Toluidine Blue Stain (Kit)

Toluidine Blue Stain is a versatile, basic dye used extensively in histology and cytology for the visualization of cellular structures, particularly in tissue samples with high nucleic acid content. Known for its ability to stain a variety of tissue components, Toluidine Blue is most commonly used for examining cartilage, mast cells, and other tissues with high proteoglycan content. The stain imparts a rich blue color to cell nuclei, while tissues with acidic components, like cartilage, show an intense metachromatic shift, making it easier to differentiate cellular components under the microscope.
