  • Polynucleotide encoding an IL-29 polypeptide
    Patent number: 7582450
    Abstract: Homogeneous preparations of IL-28A, IL-28B, and IL-29 have been produced by mutating one or more of the cysteine residues in the polynucleotide sequences encoding the mature proteins. The cysteine mutant proteins can be shown to either bind to their cognate receptor or exhibit biological activity. One type of biological activity that is shown is an antiviral activity.

  • IL-21 production in prokaryotic hosts
    Patent number: 7250274
    Abstract: The expression vectors and methods using an E. coli expression system for the large scale production of IL-21 are described. The vectors utilize the IL-21 coding sequence with specific changes in nucleotides in order to optimize codons and mRNA secondary structure for translation in E. coli. Using the expression vectors, the IL-21 gene was produced in E. coli to a level of greater than 1 g/L in fed batch fermentation. Also included are OmpT deficient E. coli strains transformed with an IL-21 expression vector.
