Application

Somatostatin has been used in cell culture. It has also been used in the study of glucose-6-phosphate dehydrogenase activity in monolayer cultures of thyroid epithelial cells.

Biochem/physiol Actions

Somatostatin regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones.
Somatostatin (SST) is a peptide. It performs several functions like anti-proliferation, pro-apoptosis and anti-migration. Somatostatin performs physiological activities with the help of various G protein-coupled receptor subtypes (SST receptor (SSTR)-1, SSTR2A, SSTR2B, and SSTR3–5).

Physical form

powder-0 °C; stock-frozen in working aliquots, avoid repeated freeze/thaw

Reconstitution

To prepare 2 μg/ml stock solution, dissolve in 5 ml sterile culture medium per μg somatostatin.
