Abstract:
Fluorescence bioimaging has recently jumped into a new area of spatiotemporal resolution and sensitivity thanks to synergistic advances in both optical physics and probe/biosensor design. This review focuses on the recent development of genetically encodable fluorescent reporters that bind endogenously present or exogenously applied fluorogenic chromophores (so-called fluorogens) and activate their fluorescence. We highlight the innovative engineering and design that gave rise to these new natural and synthetic fluorescent reporters, and describe some of the emerging applications in imaging and biosensing.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
