A solid-phase affinity labeling method for target-selective isolation and modification of proteins

Solid-phase affinity labeling of a target protein, peanut agglutinin (PNA), with the specifically designed chemical tool 1 selectively and effectively furnished the labeled PNA. Furthermore, this method was applicable to native human carbonic anhydrase II in red blood cell lysate using the chemical tool 2 without the need for tedious manipulations.
