Six-reagent melanin and argentaffin granules staining kit
Masson Fontana kit is used in a specific method for proving argentaffin granules in histological sections, based on reduction of silver nitrate to elemental silver.
Melanin is pigment usually found in skin, hair, retina, and some parts of central nervous system. In order to avoid getting false positive results, Masson Fontana kit contains reagents for melanin depigmentation. Depigmentation is conducted on a control section before impregnation using silver
Result
Melanin, argentaffin granules - black (diagnosis assessment section); black color is not present in the control section because of the melanin depigmentation process
Nuclei - red
