General description
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.
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.
Biochem/physiol Actions
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.
