Background
Details
Gastrin-secreting cells are numerous in the antrum and a few are found in the proximal duodenum. The antibody can be used for the diagnosis of gastrin-producing tumors which are mainly found in the pancreas and occasionally in the stomach and the duodenum.
Absorption with 10 – 100 µg gastrin 1-34 and CCK 8 per ml antiserum abolishes the staining.
Positive control: Formalin-fixed paraffin sections of rat antrum.
