General description

Trypan blue (C.I. 23850) for microscopy, is a dry dye for the preparation of a color staining solution, staining histological sample material of human origin, e.g. trichrome staining in collagenous connective tissue. The dye has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining.
