Abstract

A new improved glycoprotein having erythropoietin-type activity is disclosed. The substrate is characterized by amino acid sequence substantially identical to the amino acid sequence of native human erythropoietin wherein the methionine-54 is replaced with leucine. DNA encoding for the EPO-substance and expression vectors incorporating the same are disclosed. Therapeutic compositions and methods for treatment of anemic conditions are described.
