Erythropoietin (EPO) is a glycoprotein hormone essential for erythropoiesis and red blood cell production. Recombinant EPO and erythropoiesis-stimulating agents (ESAs) such as epoetin alfa and darbepoetin are widely used to treat anemia in chronic kidney disease, oncology, and HIV patients. However, ESA therapy can induce anti-EPO neutralizing antibodies, leading to complications like pure red cell aplasia (PRCA). Catalina’s high-quality EPO antibodies are useful for studies of EPO detection, erythropoietin signaling pathways, immunogenicity monitoring, anemia pathophysiology, and therapeutic antibody development. Our EPO antibodies deliver reliable and reproducible results, making them powerful tools for hematology, nephrology, diagnostics, and translational medicine.
