The Methyl Green (CI 42590) Analytical Grade by Dinâmica, available at LojaLab, is a basic triarylmethane dye used mainly in histology and cytology to visualize DNA-rich structures. The CAS 7114-03-6 form is supplied as a zinc-chloride-containing complex represented by C27H35BrClN3.ZnCl2. In Methyl Green-Pyronin techniques, Methyl Green stains chromatin and nuclei while pyronin reveals RNA-rich components, provided fixation, pH, differentiation and dye quality are appropriate. Crystal Violet contamination, pH changes and degradation may impair selectivity and color.
