Used in biomedical research to quantify erythroferrone (ERFE) levels in human serum and plasma samples. Helps investigate iron metabolism regulation, particularly in conditions like anemia, thalassemia, and hemochromatosis. Supports studies on erythropoiesis and the body's response to hypoxia or increased red blood cell production. Commonly applied in clinical labs and research settings to understand ERFE's role in inflammation and chronic kidney disease. Enables evaluation of therapeutic interventions targeting iron disorders.
