Aptamer‐Based Affinity Labeling of Proteins

A most able label: Labeled aptamers (see picture) can be cross-linked to their target structures in a light-dependent and highly specific manner as a result of a new strategy termed aptamer-based affinity labeling (ABAL) of proteins. The aptamer–protein complexes can be enriched in vitro, from a cellular lysate and from the surface of living cells, opening new ways to study aptamer interactions in biological contexts.
