Nanocs Aminooxy PEG derivatives, also called Oxyamine PEGs, are one of Nanocs aldehyde or ketone reactive PEG derivatives that can react with polysaccharides or glycoproteins. Reaction between aminooxy PEG and aldehyde/ketone forms an oxime bond which can be further reduced by Sodium Borohydride (NaBH4) to form a more stable linkage. Our Aminooxy PEG derivatives cover a broad range of different functionalities including DSPE PEG aminooxy, Aminooxy PEG Biotin, Aminooxy PEG Maleimide, Aminooxy PEG thiol, Aminnoxy PEG FlTC, DBCO PEG aminooxy, Azide PEG aminnoxy, SPDP PEG aminooxy and many others.
