Erythropoietin/EPO is a renal cytokine that activates Akt and NF-κB signaling pathways by binding to erythroid progenitor cells EPOR. Erythropoietin/EPO regulates erythroid proliferation and differentiation and inhibits apoptosis. Erythropoietin/EPO also has angiogenic ability comparable to VEGF and can stimulate endothelial cell capillary sprouting. Erythropoietin/EPO can be used in the study of ischemic heart diseases such as anemia in end-stage renal disease. Erythropoietin/EPO Protein, Human (CHO) is a recombinant Erythropoietin/EPO protein expressed in CHO cells with tag-free.
