The application of this tagging system to image proteins in live cells would offer significant opportunities to track cellular events with minimal spatial and functional perturbation on a protein of interest. However, previously reported Ni-NTA\u2013based probes suffer from poor membrane permeability and have been limited to label membrane proteins only.
