new strains of XenoMouse mice demonstrates our commitment to maintaining technological leadership in the antibody field said. XenoMouse strains include germline-configured, megabase-sized YACs carrying portions of the human IgH and Igkappa loci, including the majority of the variable region repertoire, the genes for Cmicro, Cdelta and either Cgamma1, Cgamma2, or Cgamma4, as well as the cis elements required for their function. The IgH and Igkappa transgenes were bred onto a genetic background deficient in production of murine immunoglobulin. The major impediment to the development of murine monoclonal antibodies (mAbs) for therapy in humans has been the difficulty in reducing their potential immunogenicity. "Hide abgenix and the xenomouse by Robert. Abgenix licensed the lambda light chain genes and obtained certain related materials from the Medical Research Council of the United Kingdom to make this new strain of XenoMouse animals. Our comprehensive program of antibody technologies, which includes the XenoMouse and XenoMax platforms, intrabodies and catalytic antibodies, provides Abgenix and its collaborators with state-of-the-art tools for creating antibody-based therapeutic products.'. Introduction of the complete lambda light chain locus, containing 30 functional V genes, by Abgenix scientists extends the earlier achievement. Using rapid microplate-based assays to measure and rank antibodies according to design goals (e.g., potency, affinity, specificity individual B-cells producing extremely high-quality antibodies can be identified and the antibody encoding genes recovered.
Abgenix xenomouse essay
Approximately 40 of human antibodies have lambda light chains (Ig lambda) and the other 60 have kappa light chains (Ig kappa). Abgenix's XenoMax(TM) technology allows researchers to rapidly scan the majority of the immune repertoire of an immunized XenoMouse animal, and to identify B-cells that produce antibodies with the desired functional properties and the optimum affinities.
The utility of XenoMouse strains for the generation of large panels of high-affinity, fully human mAbs can be made available to researchers in the academic and private sectors, and should accelerate the development and application of mAbs as therapeutics for human disease. Abgenix has to decide whether to sell the software development of large pharmaceutical company or enter into a joint venture to push the product forward. Announced today at the IBC Antibody Engineering Conference in San Diego, Calif., the launch of new versions of XenoMouse mice that produce fully human monoclonal antibodies that contain both lambda and kappa light chains. Dolan Source: Harvard Business School 14 pages. Abgenix expects these strains of mice, making both human IgG kappa and human IgG lambda monoclonal antibodies, to expand significantly the number and diversity of XenoMouse-derived antibody product candidates teenage values essay for its collaborators and for itself. The XenoMouse animal's immune system still recognizes human antigens as foreign, but instead of producing mouse antibodies it produces fully human antibodies. The purpose of adding the human Ig lambda(lambda light chain genes) to XenoMouse strains of mice is to capture and to mimic more completely the full repertoire of the human antibody response.
