  • IL-2 analogs containing N-linked glycosylation sites
    Patent number: 5153310
    Abstract: Biologically active analogs of human IL2, which differ from natural IL2 by the substitution of amino acid residues to form N-linked glycosylation sites in the molecule, are prepared by recombinant DNA techniques. Such analogs of IL2 are N-linked glycosylated when expressed in eukaryotic cells. Natural IL2 is not N-linked glycosylated.
