Matched Pair Detection Set. Detects human Erythroferrone [Myonectin; CTRP15] in serum, plasma and cell culture supernatant. Colorimetric sandwich assay. Sample types: Cell Culture Supernatant, Plasma, Serum. Range: 0.156 to 10ng/ml. Erythroferrone plays two different regulatory role.s: i) As a myokine, Erythroferrone/Myonectin acts as an endurance exercise-driven myokine which protects the heart from ischemic injury by reducing cardiomyocyte apoptosis and macrophage inflammatory response, and ii) Erythroferrone is produced by erythroblasts after bleeding or EPO treatment and acts on hepatocytes to suppress hepcidin expression, resulting in increased release of iron from cellular iron stores. Erythroferrone acts on hepcidin by inhibiting members of the BMP-5, BMP-6 and BMP-7 subgroup of BMPs. Erythroferrone functions as erythroid modulator of iron metabolism and hemoglobin synthesis.
