Patents Assigned to Ambrx
  • Publication number: 20110269974
    Abstract: The invention provides water-soluble compounds that include a polymer and at least one terminal azide or acetylene moiety. Also provided are highly efficient methods for the selective modification of proteins with PEG derivatives, which involves the selective incorporation of non-genetically encoded amino acids, e.g., those amino acids containing an azide or acetylene moiety, into proteins in response to a selector codon and the subsequent modification of those amino acids with a suitably reactive PEG derivative.

  • Patent number: 7959926
    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.
