Lipoic acid PEG Aminooxy

Synonym: Aminooxy PEG Lipoic acid, Oxyamine PEG Lipoic acid, Hydroxyamine PEG Lipoic acid, Lipoic acid-PEG-ONH2.

Description:

Lipoic acid PEG Aminooxy (Lipoic acid-PEG-ONH2) is one of Nanocs carbonyl reactive PEG derivatives that have a lipoic acid group on one end of PEG and an aminooxy group (-ONH2) on the other terminus. Lipoic acid, also known as thioctic acid, contains a disufide bond that can bind to gold and other metal surface. It is also an important molecule parting in various biological processes. Aminooxy group (-ONH2), on the other hand, can react with aldehyde or ketone groups derived from polysaccarides or glycoproteins. Reaction between aminooxy and ketone group results in a stable oxime linkage, which is more stable than the schiff base formed between amine and ketone group.
