Description

General description

Methyl Blue is a triaminotriphenylmethane dye, widely used in paper, textile and leather production.

Application

Methyl Blue has been used:

• to stain leaf disks for callose visualization within the cells
• to incubate cells for 4′,6-diamidino-2-phenylindole (DAPI)/septa staining
• as a marker for β-(1-3)-d-glucans or acidic phloroglucinol for the detection of callose and lignin

Biochem/physiol Actions

Methyl Blue is considered as a xenobiotic compound and has antiseptic property. It is useful in polychrome staining. Methyl blue is mostly used for staining samples in histology and microbiology. It is also useful as a model to reveal the role of catalyst in light induced degradation of dyes.
