Abstract
We report on new fluorogenic HaloTag probes based on a molecular rotor design. Thanks to their viscosity-sensitive emission, the probes light-up upon reaction with the protein self-labeling tag HaloTag. The palette of probes cover an emission range from green to red and exhibit remarkably low non-specific signal that enabled wash-free targeted imaging of intracellular organelles and proteins with good contrast in live Hela cells.
