Description

Description générale

Methyl Violet 2B is a mixture of polymethylated (4,5 and 6) pararosaniline chlorides

Application

Methyl violet 2B has been used to stain human lung fibroblast cells (A549) in in vitro antiviral assay.

Actions biochimiques/physiologiques

Methyl violet 2B is a cationic dye with a triphenylmethane structure. It acts as a selective dye and facilitates the differentiation of Klebsiella pneumoniae from Enterobacter aerogenes and other gram-negative organisms. Methyl violet 2B is harmful if inhaled, swallowed or absorbed through skin, contact may cause damage to skin and eyes. Hence, the dye removal is of great importance.

Adéquation

Certified for use in Flemming triple stain with iodine for chromosomes; Newton′s crystal violet-iodine technique for chromatin and nucleoli; Lieb′s amyloid stain.
