EPO, also known as erythropoietin, is a glycoprotein hormone in the type I cytokine family and is related tot hrombopoietin. It is primarily produced in the kidney by a population of fibroblast-like cortical interstitial cells adjacent to the proximal tubules. This protein can be found in the plasma and regulates red cell production by promoting erythroid differentiation and initiating hemoglobin synthesis. It also has neuroprotective activity against a variety of potential brain injuries and anti-apoptotic functions in several tissue types. Recombinant protein corresponding to aa27-192 from mouse Erythropoietin, fused to His-Tag at C-terminal, expressed in Baculovirus.
