Fluorescence

      Accurate interpretation of FRET states often requires fluorophores that do not easily photobleach and are resistant to blinking. Without such conditions, poor signal-to-noise can confound data interpretation and reproducibility. To address these short comings, we have recently developed self-healing fluorophores which result in longer-lived fluorescence with minimal blinking. These fluorophores allow smFRET data to be acquired over long time courses at millisecond time resolution thereby affording the ability to capture rare conformational dynamics that occur on fast timescales.
