Methyl green-pyronin stain

From Wikipedia, the free encyclopedia

Methyl green-pyronin (MGP) is a classical histological staining technique using two basic (cationic) dyes for the demonstration and differentiation of DNA and RNA. Methyl green is specific for phosphate radicals in the DNA double helix staining it green-blue. does not possess this affinity and binds to the remaining negatively charged RNA staining it red. The method is useful in identifying the distribution of Nissl substance in neuronal cell bodies.[1]
