Urotensin II, mouse TFA（Cat No.:I045885）, is a cyclic peptide and the natural ligand of the urotensin II receptor (UT), a G-protein–coupled receptor regulating vascular tone, cardiac function, and renal physiology. Supplied as a trifluoroacetate (TFA) salt for stability, it is widely used in experimental models to study hypertension, heart failure, and vascular remodeling. Mouse Urotensin II TFA also aids in investigating metabolic and renal disorders linked to aberrant UT signaling. This peptide provides a powerful research tool for cardiovascular biology and therapeutic strategy development.
