  • Patent number: 5731193
    Abstract: Insertion of IFN-alpha promoters in recombinant DNAs improves their expression efficiencies for useful polypeptides. Expression of such a recombinant DNA in host cells of mammalian origin is artificially controllable by the presence and absence of external stimuli using IFN-alpha inducers. Thus, transformants with such a recombinant DNA readily increase to a maximized cell density with causing neither damages nor extinction due to polypeptides they produce, and subsequent exposure to IFN-alpha inducers allows the proliferated cells to efficiently produce polypeptides with significant glycosylations.
