title: Radio-immunoassay of somatostatin from isolated rat pancreatic islets.
abstract: Certain aspects of radio-immunoassay of somatostatin from isolated rat pancreatic islets are described. Somatostatin-14, and not somatostatin-28, is secreted from isolated rat pancreatic islets. Less somatostatin secretion is measured per islet owing to purity of tracer in the radio-immunoassay. Theophylline apparently cross-reacts with somatostatin in the assay described, and this has to be taken into consideration when studying somatostatin release induced by theophylline in isolated islets.
