Used in biomedical research to quantify Epiregulin (EREG) levels in biological samples such as serum, plasma, and cell culture supernatants. Helps in studying the role of EREG in cell proliferation, differentiation, and tissue repair. Widely applied in cancer research, particularly in understanding tumor growth and progression in epithelial cancers. Also utilized in immunology and inflammatory disease studies due to EREG's involvement in immune cell regulation. Provides a reliable, sensitive, and specific method for detecting low concentrations of EREG, supporting both basic research and biomarker validation.
