Ricky Lieu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods for expression and purification of recombinant human growth hormone
    Patent number: 8178108
    Abstract: The present invention relates generally to the production, purification, and isolation of human growth hormone (hGH). More particularly, the invention relates to the production, purification, and isolation of substantially purified hGH comprising non-naturally encoded amino acids and hGH from recombinant host cells or culture medium including, for example, yeast, insect, mammalian and bacterial host cells. The process of the present invention is also useful for purification of hGH linked to polymers or other molecules.
    Type: Grant
