Used in biomedical research to measure levels of erythropoietin in biological samples such as serum, plasma, or cell culture supernatants. Commonly applied in studies related to red blood cell production, anemia, kidney function, and doping control in sports science. Enables quantitative detection of EPO with high sensitivity and specificity, supporting both clinical research and pharmaceutical development. Widely used in laboratories to monitor EPO expression under hypoxic conditions or in response to therapeutic treatments.
