| Outline of Final Research Achievements |
In this study, a novel method was developed for producing N-terminally fluorescent-labeled IgG antibodies that show antigen-dependent fluorescence change. By reacting fluorescent-labeled aldehyde with IgG antibody under weakly acidic condition, the fluorescent group was specifically attached at the N terminus, and the resulting N-terminally fluorescent-labeled antibody showed fluorescence intensity changed upon the antigen binding. In addition, it is possible to synthesize dual-labeled fluorescence-responsive antibody that can detect the antigen-binding as a change in fluorescence intensity ratio, and to detect tagged proteins expressed in a cell-free translation system in a real-time manner.
