Melanin bleaching, antigen analysis, and DAB bleaching. A, Control sections of melanin-containing tissues were stained with hematoxylin. B, Samples containing melanin were treated with potassium permanganate (KMnO4) bleaching method. C, Samples containing melanin were treated with potassium dichromate (K2Cr2O7) bleaching method. D, Samples containing melanin were treated with TCCA bleaching method. E, Control sections of melanin-free samples were stained with antivimentin. F, Samples without melanin were treated with potassium permanganate (KMnO4) bleaching method followed by immunostaining using antivimentin antibody. G, Samples without melanin were treated with potassium dichromate (K2Cr2O7) bleaching method followed by immunostaining using antivimentin antibody. H, Samples without melanin were treated with TCCA bleaching method followed by immunostaining using antivimentin antibody. I, Control sections of melanin-free samples were stained with antivimentin. J, Samples without melanin were treated with potassium permanganate (KMnO4) bleaching method after immunostaining using antivimentin antibody. K, Samples without melanin were treated with potassium dichromate (K2Cr2O7) bleaching method after immunostaining using antivimentin antibody. L, Samples without melanin were treated with TCCA bleaching method after immunostaining using antivimentin antibody.
