Description
Ethanol solutions of martius yellow have been used to stain erythrocytes yellow, so they contrast well with red fibrin, in trichrome methods such as Lendrum's Picro Mallory and Slidder's Martius, Scarlet, and Blue (MSB). It can be combined with other small molecular weight yellow dyes to increase stain intensity.
The sodium salt of martius yellow is the dye Manchester yellow with an absorption maximum of 432 (Aldrich).
