Angiotensin II human TFA（Cat No.:I044393）is a synthetic peptide corresponding to the human form of angiotensin II, a key effector in the renin-angiotensin system (RAS), presented as the trifluoroacetate (TFA) salt. It plays a critical role in regulating blood pressure, fluid balance, and vascular tone by binding to angiotensin receptors, particularly AT1. This peptide is widely used in cardiovascular research to study hypertension, vasoconstriction, and heart failure mechanisms. The TFA salt enhances stability and solubility, making it suitable for in vitro and in vivo experiments exploring RAS-related pathophysiology and drug development.
