Toluidine Blue - Histological Applications

Certified 0.1% toluidine blue O supports mast cell identification, cartilage staining, and amyloid demonstration across anatomic pathology workflows.

Histology laboratories demonstrate mast cell degranulation through purple metachromasia. Granule staining quantifies allergic inflammation across dermatopathology specimens.

Orthopedic pathology reveals chondrocyte lacunae and territorial matrix. Metachromatic cartilage staining differentiates benign from malignant chondrosarcoma.

Quality control confirms dye content (spectrophotometry), pH 4.0-4.5 stability, and metachromatic sensitivity. Aqueous formulation prevents alcohol extraction artifacts.

Dropper bottles enable precise staining gradients. Light-stable solution maintains performance across multi-user microscopy facilities.
