We present an effective, fast and user-friendly method to reduce co-digestion of bead-bound ligands, such as antibodies or streptavidin, in affinity purification-mass spectrometry experiments. A short pre-incubation of beads with Sulfo-NHS-Acetate leads to chemical acetylation of lysine residues, ma...
