詳細

詳細

Methyl blue (C.I.42780), is a dry dye for the preparation of a color staining solution used for the polychrome staining of histological tissue sections of human origin. The dye has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining.
