The Fontana-Masson stain is intended for use in the histological visualization of melanin pigment in FFPE sections. Melanin is a nonlipid, no hematogenous pigment present in the hair, skin, retina and iris. This stain is particularly useful for identifying melanocytes and melanotic tumors. The method involves using silver-based reagents that bind to melanin, making it visible under a microscope.
