Vasopressin (arginine vasopressin, AVP) is a nine-amino-acid cyclic neurohypophyseal hormone that regulates water reabsorption, vascular tone and social behavior through V1a, V1b and V2 receptors. Its multiple receptor actions support wide-ranging studies in renal physiology, cardiovascular regulation and behavioral neuroscience. This product is a white lyophilized powder at >=99% HPLC purity in a sealed vial. Batch-specific quality data and dependable cold-chain delivery are provided. Vasopressin is a neurohypophyseal peptide studied in endocrinology and physiology research on water balance, vascular tone and the regulation of antidiuresis, where its receptor pathways are a central focus. Investigators use it in receptor-binding assays, isolated-tissue experiments and in vivo models measuring blood pressure and urine output. The lyophilized product reconstitutes in physiological buffer, and our batch documentation supports accurate reporting of purity and handling. We offer both research and bulk quantities, professional packaging, and a support team that assists with specifications and international logistics. Receptor and functional studies often require precise dosing, and our batch documentation records purity and content so that results can be reproduced across experiments. We keep stock stable for repeat orders and provide packing that protects the lyophilized powder in transit. Research and bulk quantities are both available, and our team assists with reconstitution guidance and international shipping arrangements to support physiology and endocrinology laboratories worldwide. Orders are processed promptly after confirmation, with professional packaging that protects lyophilized material during transit. We support both trial quantities for evaluation and bulk volumes for ongoing research programs, with dedicated after-sales assistance at every step.
