  • Patent number: 4970161
    Abstract: A DNA sequence on which a chromosomal DNA sequence coding for human interferon-.gamma. (HuIFN-.gamma.) and having a TATA box is ligated to a sequence of a promoter. Cell cultures transformed with said DNA revealed a higher expression of HuIFN- than cell cultures transformed with a DNA which does not have such TATA box. When transformed with said DNA, cell cultures produced HuIFN-.gamma. in a serum free medium. Transformed cell cultures derived from blood cells of HuIFN-.gamma. resistant human cell-line also could produce HuIFN-.gamma..
