Used in diagnostic assays to detect and quantify erythropoietin receptor (EPOR) expression in clinical samples, particularly in cancer research where EPOR signaling is linked to tumor progression. Employed as a control antibody in immunoassays to validate target specificity and assay performance. Supports development of therapeutic anti-EPOR drugs by providing a standardized reference for binding characteristics. Widely applied in flow cytometry, immunohistochemistry, and Western blotting to study erythropoiesis and anemia-related disorders. Also utilized in pharmacokinetic and pharmacodynamic studies to monitor receptor occupancy in response to erythropoiesis-stimulating agents.
