This approach requires engineering the protein of interest with a tetracysteine tag and applying a compatible chemical labeling strategy in living cells.; requires tagged proteins rather than native unlabeled proteins
The abstract indicates a remaining need for selective labeling of non-tagged, native proteins in complex mixtures.
