Recombinant proteins containing four cysteines at the i, i + 1, i + 4, and i + 5 positions of an alpha helix were fluorescently labeled in living cells by extracellular administration of 4',5'-bis(1,3, 2-dithioarsolan-2-yl)fluorescein. This designed small ligand is membrane-permeant and nonfluorescent until it binds with high affinity and specificity to the tetracysteine domain. Such in situ labeling adds much less mass than does green fluorescent protein and offers greater versatility in…
