Crystal violet is a triarylmethane dye.

In Vitro

Crystal Violet is a component of Gram staining that allows one to recognize the difference between gram-positive and gram-negative bacteria with differential staining. The compound helps to access bacterial contamination of tissue culture samples. The staining response is due to the difference in the chemical and structural composition of the cell walls in different bacteria. Crystal Violet can also be used to test the different species of archaea and the cytostatic/cytotoxic effects on tumor cell lines [1][2][3].
