Methyl Green zinc chloride salt Usage And Synthesis

Description

Methyl Green, Zinc chloride salt (chemical formula: C27H35Cl4N3Zn) is the zinc chloride salt form of Methyl green. Methyl green is a cationic or positive charged stain. Since it can binds selectively to the AT-rich regions of native DNA, it is mainly used for the DNA and RNA staining in the cell nuclei. Methyl Green, Zinc chloride Salt, as a CERTISTAIN® dry dye for DNA staining, it has many application: used as a tracking dye in acid buffers for electrophoresis; used to demonstrate DNA and RNA in tissues sections in the Methyl Green-Pyronin method; used as an exclusion viability stain for cells. In addition, it can also be used in fluorimetric assay and flow cytometry.
