Used in biomedical research to quantify β-epidermal growth factor receptor (β-EPR) levels in human biological samples such as serum, plasma, and cell culture supernatants. The kit enables detection of biomarkers associated with epithelial cell regulation, wound healing, and certain cancers. It is widely applied in clinical laboratories and pharmaceutical research for monitoring disease progression and evaluating therapeutic responses. The assay supports high sensitivity and specificity, making it suitable for studies involving signal transduction pathways and receptor activation in human tissues.
