Methyl Green zinc chloride salt

Marker dye for DNA in acid and neutral media. Methyl green is mainly used as a DNA stain in histochemistry. At low concentrations it binds selectively to AT-rich regions of native DNA. At high concentrations it is present at all available DNA sites. Methyl Green is used as a tracking dye in acid buffers for electrophoresis. It helps differentiate bacteria and is also a tissue stain for nucleoli and mitochondria in tissues. Spectral data: Absorption maxima = 630-635nm. May be used as a pH indicator with a pH range = pH 0.2(yellow) to pH 1.8(blue). Product References: (1) H. Lyon, et al., Histochem. J. 24, 224 (1992) , (2) S.K. Kim & B.
