PEG PFP ester

PEG PFP ester

PEG PFP ester is a class of crosslinking reagent with similar applications as the NHS esters,  but are more stable in aqueous solution.  Reaction of the PEG PFP ester with amine group form a stable, irreversible amide bond.   It can be used either in homobifunctional or heterobifunctional labelling such as surface modification on nanoparticles and cells.
