Maldonado-San Jose stain

A near-extinct histologic method using phloxine, azure B and hematoxylin, in sequence, to differentiate the cell types in the pancreatic islets. It has been largely superseded by specific immunocytochemical methods for the identification of insulin, glucagon, somatostatin and pancreatic polypeptide within islet cells.
