title: Simultaneous protein tagging in two colors.
abstract: The fluorescent tagging of proteins in the natural environment of the cell is an emerging technique in cell biology. In this issue of Chemistry & Biology, Gautier et al. introduce a fluorescent labeling procedure orthogonal to existing ones, enabling tagging of two different proteins in living cells.
