    摘要: This invention relates to prostate-specific membrane antigen (PSMA) antibodies and antibody drug conjugates comprising at least one non-naturally-encoded amino acid. Disclosed herein are αPSMA antibodies with one or more non-naturally encoded amino acids and further disclosed are antibody drug conjugates wherein the αPSMA antibodies of the invention are conjugated to one or more toxins. Also disclosed herein are non-natural amino acid dolastatin analogs that are further modified post-translationally, methods for effecting such modifications, and methods for purifying such dolastatin analogs. Typically, the modified dolastatin analogs include at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Further disclosed are methods for using such non-natural amino acid antibody drug conjugates, dolastatin analogs, and modified non-natural amino acid dolastatin analogs, including therapeutic, diagnostic, and other biotechnology uses.

    摘要: This invention provides compositions and methods for producing translational components that expand the number of genetically encoded amino acids in vertebrate cells. The components include orthogonal tRNA's, orthogonal aminoacyl-tRNA synthetases, orthogonal pairs of tRNA's/synthetases and unnatural amino acids. Proteins and methods of producing proteins with unnatural amino acids in vertebrate cells are also provided. The present invention provides vertebrate cells with translation components, e.g., pairs of orthogonal aminoacyl-tRNA synthetases (O-RSs) and orthogonal tRNA's (O-tRNA's) and individual components thereof, that are used in vertebrate protein biosynthetic machinery to incorporate an unnatural amino acid in a growing polypeptide chain, in a vertebrate cell.
