Used in biomedical research to quantify human epithelial regulatory protein (EREG) levels in cell cultures, tissue extracts, and biological fluids such as serum or plasma. Enables researchers to study EREG's role in cell proliferation, tissue repair, and inflammation. Commonly applied in cancer research, particularly in studies involving epithelial-derived tumors like lung, breast, and colorectal cancers, where EREG expression may influence tumor growth and response to therapy. Also utilized in immunology and dermatology research to investigate epithelial cell regulation and signaling pathways. The kit supports high-throughput screening in drug development and biomarker validation studies.
