  • Publication number: 20150291941
    Abstract: Pseudomonas exotoxin A or “PE” is a 66 kD, highly potent, cytotoxic protein secreted by the bacterium Pseudomonas aeruginosa. Various forms of PE have been coupled to other proteins, such as antibodies, to generate therapeutically useful cytotoxin conjugates that selectively target cells of a desired phenotype (such as tumor cells). In the present invention, peptides spanning the sequence of an approximately 38 kD form of Pseudomonas exotoxin A protein were analyzed for the presence of immunogenic CD4+ T cell epitopes. Six immunogenic T cell epitopes were identified. Residues were identified within each epitope for introduction of targeted amino acid substitutions to reduce or prevent immunogenic T-cell responses in PE molecules which may be administered to a heterologous host.

  • Patent number: 9115361
    Abstract: A method for using cloning vector plasmids to produce DNA molecules, such as transgenes, in a single cloning step. The transgenes can be used for the purpose of gene expression or analysis of gene expression. The plasmid cloning vectors are engineered to minimize the amount of manipulation of DNA fragment components by the end user of the vectors and the methods for their use. Transgenes produced using the invention may be used in a single organism, or in a variety of organisms including bacteria, yeast, mice, and other eukaryotes with little or no further modification.
