Vasopressin, also known as Arginine Vasopressin (AVP), is a synthetic nonapeptide hormone that regulates water reabsorption and vascular tone, studied in renal and neuroendocrine research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Vasopressin is investigated in research on osmoregulation, blood-pressure control and receptor signaling, and is commonly applied in cell-based and preclinical studies. The lyophilized format ensures stable reconstitution and consistent dosing. All batches undergo rigorous quality testing and batch-specific COA documentation can be provided on request. Store unopened vials sealed at 2-8 degree C, away from light and humidity; for longer preservation store at -20 degree C without repeated freeze-thaw cycles. Trial orders and bulk supply are supported, with OEM, private-label and secure neutral packaging available for global delivery. For research use only.
