Somatostatin is a cyclic 14-amino-acid peptide hormone that inhibits the release of many hormones, including growth hormone, insulin and glucagon, studied in endocrine research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Somatostatin is investigated in research on hormone regulation, neurotransmitter signaling and somatostatin-receptor pharmacology, and is commonly applied in cell-based and preclinical studies. The freeze-dried presentation provides good stability and reproducible reconstitution for consistent experimental dosing. Quality control is performed on each batch with batch COA available on request. Keep the product sealed at 2-8 degree C, protected from light and moisture; for long-term storage -20 degree C is recommended and repeated thawing should be avoided. We accept both sample and bulk orders, offer OEM and private label service, and arrange discreet neutral packing for worldwide shipping. Intended for laboratory research only, not for human or veterinary application.
