  • Process for preparing recombinant proteins using highly efficient expression vector from saccharomyces cerevisiae
    Patent number: 6391585
    Abstract: This invention concerns a method of producing human granulocyte colony-stimulating factor (hGCSF) and human growth hormone (hGH) from least by using recombinant DNA technology. More specifically, this invention relates to a method of producing hGCSF or hGH by using yeast expression vector which contains: hybrid promoters comprising promoters of two different yeast-derived genes, yeast killer toxin leader peptide, and amino terminus of IL-1&bgr;. In addition, this invention relates to a method of producing hGCSF by using expression vector which contains promoter and secretion signal of HSP 150.
