Aminooxy PEG derivatives are one of aldehyde or ketone reactive PEG derivatives that can react with polysaccharides or glycoproteins. The 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. 
Biochempeg provides a broad range of Aminooxy PEG derivatives with various functional groups, such as Amine (NH2), Thiol (SH), Azide (N3), NHS ester, Maleimide (Mal), Carboxylic Acid (COOH), AlKyne, Silane, Biotin, DBCO, DSPE, etc.
