Angiotensin II is an octapeptide hormone that potently activates AT1 and AT2 receptors, playing a central role in blood-pressure and fluid-balance research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Angiotensin II is investigated in research on vascular tone, aldosterone secretion, renal function and G-protein-coupled receptor signaling, and is commonly applied in cell-based and preclinical studies. The lyophilized format ensures high stability and easy reconstitution for reproducible experimental dosing. Strict quality control is applied to every production batch, and we can supply batch-specific COA documents upon request. Unopened material should be stored sealed at 2-8 degree C in a dry, dark place; for longer storage -20 degree C is advised while avoiding repeated freezing and thawing. We support trial orders and large-volume supply, with OEM and custom private-label options and discreet worldwide shipping available. For research purposes only, not for human or veterinary use.
