Demonstration of insulin in the pancreas of the Didelphis albiventris (opossum) by immunocytochemical techniques.
The exocrine secretion of insulin by the suckling opossum was demonstrated by indirect immunofluorescence and immunoperoxidase techniques. In weanling and adult marsupial insulin is present in the pancreatic islets and in scattered cells located in the exocrine secretory units. Positive reaction was also observed in the brush border and in some isolated cells of the proximal segment of the suckling opossum small intestine.
