A process for extending the half-life in vivo by a biologically active protein or peptide, characterized by covalently coupling said protein or peptide to a polypeptide fragment capable of binding to a serum protein, whereby when administering the resulting protein or peptide congugate its binding to the serum protein results in extended biological activity; the use of the protein or peptide conjugate above for manufacturing a medicament which, when administered to a mammal including man, shows extended half-life in vivo; and a method of therapeutic or prophylactic treatment. |
