Description

Amino Acid Sequence

Ala-Gly-Cys-Lys-Asn-Phe-Phe-Trp-Lys-Thr-Phe-Thr-Ser-Cys

Biochem/physiol Actions

Somatostatin regulates endocrine function and cell proliferation via interaction with G-protein-coupled somatostatin receptors. It exists in two active forms produced by alternative cleavage of a single preproprotein (14 aa and 28 aa forms). Somatosatin inhibits the release of growth hormone; thyroid-stimulating hormone and a range of gastrointestinal hormones: Cholecystokinin (CCK); Enteroglucagon; Gastrin; Gastric inhibitory polypeptide (GIP); Motilin; Secretin; Vasoactive intestinal peptide (VIP).

Physical form

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

Reconstitution

To prepare 2 μg/ml stock solution, add 10 ml sterile culture medium.
