Atrial Natriuretic Peptide (1-28) (human) trifluoroacetate salt is primarily used in research to study cardiovascular and renal functions. It is employed to investigate its role in regulating blood pressure, fluid balance, and sodium excretion. Researchers use it to explore its effects on vasodilation, diuresis, and natriuresis, which are critical in understanding hypertension and heart failure. Additionally, it serves as a tool in pharmacological studies to develop therapeutic agents targeting the natriuretic peptide system for treating cardiovascular diseases. Its application extends to in vitro and in vivo experiments to assess its biological activity and mechanisms of action.
