Immunolocalization of Kallikrein in Porcine Pancreas at the Ultrastructural Level

Abstract
The immunological localization of kallikrein in porcine pancreatic tissue was investigated by an immunoferritin method and presented by electronmicroscopy. Kallikrein was found in the zymogen granules of the pancreatic acinar cells as well as in the golgian area of the same cells. On the same section, all the zymogen granules of all acinar cells gave a positive reaction. Kallikrein was not found in the centroacinar or interstitial cells.
