Bombesin is a 14-amino-acid peptide originally isolated from amphibian skin that activates gastrin-releasing peptide (GRP) receptors, studied in gastrointestinal and neuroendocrine research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Bombesin is investigated in research on gut motility, satiety, neuroendocrine signaling and GRP-receptor pharmacology, and is commonly applied in cell-based and preclinical studies. The lyophilized form provides good stability and reproducible reconstitution for consistent experimental dosing. Each batch is manufactured under controlled quality systems and batch-specific certificates of analysis are obtainable on request. Store the sealed vial at 2-8 degree C away from direct light and humidity; for extended storage keep at -20 degree C and minimize freeze-thaw cycles. Small sample orders and bulk quantities are both welcomed, and we provide OEM, private-label and secure neutral-packaging services for global delivery. Laboratory research use only.
