Used in biomedical research to detect and quantify epidermal growth factor receptor (EGFR) levels in rat samples. Helps in studying EGFR expression in various tissues, particularly in models of inflammation, wound healing, and cancer. Commonly applied in preclinical studies to evaluate signaling pathway activation and the effects of therapeutic agents targeting EGFR. Enables high-throughput analysis in cell lysates and tissue homogenates with high sensitivity and specificity.
