lisa;
instead of using the bleaching, or worrying that the dab looks like melanin, protect your tissue and the results by using alk phos fast red detection. it will stain red, is permanent and can be used on almost every antibody with the exception of ER/PR and if I recall correctly(ventana will tell me if its not) Alk Phos fast Red is a bit more sensitive for detection than dab, the pathologist will adjust i assure you and morphology is saved.          dana
