  • Chemical crosslinking of intracellular proteins prior to cell lysis and immunoprecipitation
  • “Fix” protein interactions to allow identification of weak or transient protein interactions
  • Protein crosslinking to create bioconjugates via single-step reactions
  • Crosslink oriented antibodies to Protein A or G agarose
  • Immobilize proteins onto amine-coated surfaces
