Angiotensin II (3-8), human

Angiotensin II (3-8), also known as Angiotensin IV, is a peptide fragment with reduced efficacy as an agonist at the AT1 receptor compared to full-length Angiotensin II. It is utilized in research to study the renin-angiotensin system, receptor subtype specificity, and signaling pathways in both cellular and animal models.
