    摘要: The present invention provides a polyethylene glycol-conjugated erythropoietin (PEG-conjugated EPO) prepared by PEG conjugation on the lysine residue at position 52 of native erythropoietin (native EPO). In order to achieve more sustained efficacy without losing physiological activities of native EPO, a glycoprotein rich in sugar chains, there has been a need to develop a PEG-conjugated EPO with significantly sustained efficacy by introducing a controlled number of PEG molecules at controlled positions. This PEG-conjugated EPO addresses such a need and provides more sustained efficacy.
