Somatostatin, SRIF

Catalogue number: SO100

Units1 ml
Application IHC(P)

Somatostatin can be detected with this antibody in different organs like CNS, PNS, pancreas, stomach, thyroid glands and different carcinoids. Somatostatin (SRIF, GRIF) is a neuropeptide which is synthesized in the anterior hypothalamus and is transported by axonal transport to the Eminentia mediana. The release into the pituitary portal veins causes an inhibition of growth hormone secretion. Somatostatin however is also produced by endocrine cells of other organs like the C-cells of the thyroid glands, Parietal cells of the Antrum as well as by delta-cells of the pancreas. In pancreas it inhibits the the secretion of enzymes as well as Glucagon and Insulin. Some pancreatic and duodenal tumours secrete Somatostatins (Somatostatinoma). Usually this leads to diabetes in the affected patients. Somatostatin 1-14 and Somatostatin 1-28 (GRIF, SRIF).
