  • The homo bifunctional linker DBCO-PEG4-DBCO contains two DBCO moieties which enable reaction with two azides. This linker is well suited for cross linking when used in excess [1,2] but enables other interesting possibilities as circularization of biomolecules containing two azides. The hydrophilic PEG4 spacer increase water solubility needed for reaction with biomolecules in aqueous media.
