Description

Description générale

Methyl Blue (C.l. 42780) is a triaminotriphenylmethane dye with each amino group carrying a monosulfonated phenyl substituent. It is also known as Water blue, Acid blue 93, Cotton blue, Poirriers blue, and Aniline blue water soluble.

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
• in Mann′s stain as it involves a methyl blue-eosin mixture
