Outline of Final Research Achievements

Previous immunoassays have drawbacks of many steps and long time consideration. Recently we found a construction principle of recombinant antibody-based fluorescent biosensor Quenchbody (Q-body), and succeeded in detecting many targets from small molecules to large proteins by just mixing with sample. This time, by the close inspection of working principle, we developed several methodologies to turn not only recombinant but also natural antibodies to Q-bodies.
