Characterizing interactions of proteins is pivotal for understanding their function. Recently, single- molecule imaging based methods have proven useful for directly testing the stoichiometry of multi-subunit protein complexes. A limiting factor is the labeling of proteins with multiple spectrally discernible tags and low background. Here we describe a use of zinc finger-mediated protein labeling for single-molecule imaging studies in living cells. A DNA-binding zinc finger (ZF) is fused to the protein of interest and labeled by a DNA
