| Research Abstract |
With the aim of extending Quenchbody principle that can detect various antigens in a rapid and sensitive manner, an antibody binding protein probe that is fluorescence labeled at its terminus was constructed. When this probe was mixed with an anti-vimentin human Fab fragment, the dye of the probe was quenched by the Trp residues in the antibody. Moreover, when the antigen vimentin was added, dose-dependent release of the quenching was observed, thus resulted in successful detection of antigen by fluorescence increase.
