Cytochemistry Products

Sigma-Aldrich pioneered the commercial introduction of stabilized diazonium salts and substituted naphthol substrates for the cytochemical demonstration of numerous medically important cellular enzymes. In addition to the stabilized diazonium salts, Sigma-Aldrich also introduced stabilized solutions of Fast Red Violet LB base, Fast Blue BB base and Fast Garnet GBC base. The availability of stabilized base solutions allows the laboratorian to adjust working reagent volumes according to needs. Cytochemistry stains are a useful adjunct in the diagnosis of various leukemias. All kits are provided in a convenient, easy-to-use format and may be used for clinical and research purposes.
