WebTrichrome stains for connective tissue, such as Mallory and Masson, employ phos- photungstic (PTA) or phosphomolybdic (PMA) acid to 'mordant' anionic dyes, for example, Aniline Blue, to connective tissue fibres. These dyes produce beautiful pic- tures of great value to the histologist, but also erratic results.
