Used in biomedical research to quantify angiotensin II type 1 receptor levels in tissue or cell samples, this ELISA kit helps study the renin-angiotensin system's role in blood pressure regulation, cardiovascular diseases, and kidney function. It is widely applied in preclinical studies investigating hypertension, heart failure, and the effects of antihypertensive drugs. Researchers also use it to evaluate receptor expression changes under pathological conditions or after genetic manipulation. The assay enables high-throughput, sensitive, and specific detection, making it valuable in both academic and pharmaceutical research settings.
