Application

Crystal violet is used as an active component, primary stain, of Gram stain for differentiation of Gram-negative versus Gram-positive bacteria.
It has been used to check cell viability.[1] It has also been used for the staining of cells to study cell migration and invasion.[2]

Biochem/physiol Actions

Crystal violet can be used for DNA visualization in agarose gels. The dye is used only in the presence of high concentrations of DNA.[3] Crystal violet is also used for the staining of bacteria in gram staining technique.[4] It is also used for the staining of plant chromosomes.[5] Crystal Violet also helps in colorimetric measurement of cell viability.[6]

Suitability

Certified for use with the Gram stain for bacteria, Flemming triple stain with iodine for chromosomes, Lieb′s amyloid stain and Newton′s crystal violet-iodine technique for chromatin and nucleoli.
