  • Patent number: 9085611
    Abstract: Provided are a humanized monoclonal antibody against PcrV or a part thereof, and a pharmaceutical composition containing the same as an active ingredient, as an effective means for therapy of infection, particularly infection with Pseudomonas aeruginosa. Concretely, the humanized monoclonal antibody of the present invention has an excellent inhibitory activity on the cytotoxicity with respect to a target cell of Pseudomonas aeruginosa. Also, the humanized monoclonal antibody of the present invention has a high affinity for PcrV.

  • Patent number: 9080180
    Abstract: A technology for producing a pig edema disease vaccine at low cost and at high efficiency is developed. Specifically, a gene of a pig edema disease toxin protein (Stx2e protein) is efficiently expressed in plant cells to produce a plant vaccine for pig edema disease at low cost. An Stx2e protein including a secretory signal peptide derived from a plant added at an amino terminus is expressed in cells of a plant such as Lactuca sativa using the 5?-untranslated region of an alcohol dehydrogenase gene (ADH5?UTR) derived from a plant.

  • Patent number: 8883977
    Abstract: An objective of the present invention is to provide a MUC1 antibody having high specificity to cancer cells. The objective has been achieved by the present inventors who found that a cancer-specific sugar chain can be specifically recognized in MUC1 and a cancer cell expressing MUC1 having such a cancer cell specific sugar chain can be recognized. The present invention provides an antibody, an antigen-binding fragment thereof or a MUC1-binding molecule, having, for example, 40-fold specificity or more for a cancer-associated structure of MUC1 as compared to that of a normal tissue-associated structure of MUC1.
