Used in biomedical research to quantitatively measure amphiregulin levels in human biological samples such as serum, plasma, and cell culture supernatants. It is particularly valuable in studies related to immune regulation, tissue repair, and cancer progression, as amphiregulin plays a key role in epithelial cell growth, wound healing, and inflammatory responses. The kit enables researchers to assess immune cell activity, especially in conditions like asthma, inflammatory bowel disease, and viral infections. It is also employed in cancer research to investigate tumor microenvironment signaling and potential therapeutic targets.
