| Outline of Final Research Achievements |
In this study, for the development of next-generation antibody drug, we developed a novel versatile intrabody selection method, which can select intrabody against antigen protein expressed in the cytosol of mammalian cells rapidly and directly. We constructed a chimeric receptor library, which can transduce growth signal by binding to antigen, by conjugating naive library of single chain antibody scFv and intracellular domain of receptor c-kit through flexible linker G4S. We expressed this chimeric receptor library together with a model antigen, the nucleoprotein of a rabies virus, in IL-3 dependent mammalian cell Ba/F3, and successfully obtained several scFv binders against the antigen protein from proliferated cells under IL-3 deficient culture condition.
