  • Crosslink cell-surface proteins before cell lysis and immunoprecipitation
  • Identify receptor-ligand interactions by chemical crosslinking
  • “Fix” protein interactions to allow identification of weak or transient protein interactions
  • Identify near-neighbor protein interactions
  • Protein crosslinking to create bioconjugates via single-step reactions
  • Immobilize proteins onto amine-coated surfaces
