Used in research to selectively bind and inhibit the epidermal growth factor receptor (EGFR), this antibody helps study signaling pathways involved in cell proliferation and survival. It is applied in assays such as Western blotting, immunohistochemistry, and flow cytometry to detect EGFR expression in cancer cells. Due to its specificity, it supports the development of targeted cancer therapies, particularly in models of lung, colorectal, and head and neck cancers where EGFR is overexpressed. It also serves as a control or reference in comparative studies evaluating the efficacy of therapeutic anti-EGFR antibodies.
