Genetic materials such as plasmids, clone sets of bacterial artificial chromosome (BAC), recombinant adenoviruses, expression vectors, and host bacteria are the most fundamental and essential research tools. They are used in the almost all fields of the life science, from basic researches to innovations. The Gene Engineering Division collects, conducts strict quality control of genetic materials and provides domestic and international scientific community with the materials of ensured reproducibility of experimental results. We aim to facilitate life science researches and innovations for improvement of human welfare and for solution of environmental problems and hope to contribute to the sustainable development of our race. Since 2002, the Division has been selected as a core facility of DNA materials by National BioResource Project (NBRP) funded by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), Japan for collection, quality control, preservation and distribution of genetic materials of human, animal and microbe origin.

Research Subjects

  • Collection, preservation and distribution of genetic materials (DNA and cDNA).
  • Development of handling and preservation technique.
  • Development of quality control technique.
  • Development of application method of recombinant virus and its quality control.
  • Development of technology for medical sciences, biomass engineering and innovation.
