Used in biomedical research to measure levels of Angiotensin II Receptor Type 1 (AT1R) in rat samples, this ELISA kit enables quantification of receptor expression in studies related to cardiovascular function, hypertension, and renal disease. It supports investigation into the renin-angiotensin system (RAS), allowing researchers to assess changes in AT1R under experimental treatments, drug interventions, or disease conditions. Commonly applied in pharmacology and physiology labs, the kit provides a reliable tool for evaluating molecular mechanisms involved in blood pressure regulation and vascular remodeling.
