ABSTRACT:
The present invention relates to a fusion protein in which a carboxy terminal of human erythropoietin (EPO) is fused with a carboxy terminal peptide fragment of β subunit of human chorionic gonadotropin (HCG), to DNA encoding the fusion protein, and to a method for preparation of the fusion protein. The fusion protein has the enhanced in vivo activity of erythropoietin.
