There's a silverstain for melanin and other argentaffine granules: Fontana-Masson. The principle is based on the reducing effect of melanin on silverdiaminions. You can find the procedure in the AFIP manual. Gudrun

Mai 2009 20:36 An: histonet@lists.utsouthwestern.edu Betreff: [Histonet] Melanin / melanocytes staining method tintorial or IHC Craig, I was searching the archives on the histonet concerning the Dopa Oxidase stain. I have not performed this stain but have done the Schmorls stain. I was wondering if you had a particular method/protocol that you use for this stain? Are there any kits available or is it cheaper to do buying the reagents separately? Any suggestions would be greatly appreciated. Regards, Medea -- Medea J.
