endo-BCN-PEG4-PFP ester contains an PFP ester group and a BCN group on its ends. While the BCN group readily react with azide-tagged biomolecules, the PFP ester can be utilized for conjugations with amines bearing proteins, oligonucleotides, and other molecules. The hydrophilic PEG spacer increases the aqueous solubility of the resulting biomolecules.
