Abstract

This invention is directed to an erythropoietin mutein having in vivo biological activity for causing bone marrow cells to increase production of reticulocytes and red blood cells, in that the mutein is N-glycosylated at Asn38 and Asn83 but not N-glycosylated at Asn24. Such muteins have improved pharmaceutical properties.
