Used in biomedical research to measure levels of human angiotensin-converting enzyme 2 (ACE2) in biological samples such as serum, plasma, cell culture supernatants, and tissue extracts. It plays a key role in studying the renin-angiotensin system (RAS), which regulates blood pressure and fluid balance. The kit is widely used in cardiovascular research, especially in conditions like hypertension, heart failure, and kidney disease. Due to ACE2's role as the entry receptor for SARS-CoV-2, this ELISA kit is also used in COVID-19 research to monitor soluble ACE2 levels and assess viral interaction, disease progression, and potential therapeutic responses. It enables high-throughput, quantitative analysis with high sensitivity and specificity, supporting both clinical studies and drug development.
