LA-peg-Hydrazide

Lipoic acid--Polyethylene glycol--Hydrazide ,LA-peg-Hydrazide from ruixi.Lipoic acid PEG Hydrazide (Lipoic acid-PEG-CONHNH2) is one of  carbonyl reactive PEG derivatives that have a lipoic acid group on one end of PEG and a hydrazide group (-NHNH2) 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. Hydrazide group (-NHNH2), on the other hand, can react with aldehyde or ketone groups derived from polysaccarides or glycoproteins. Reaction between hydrazide and ketone group results in a stable hydrazone bond, which is more stable than the schiff base formed between amine and ketone group.LA-peg1000-Hydrazide 、LA-peg2k-Hydrazide 、LA-peg3.4k-Hydrazide and so on.We can also customize smaller molecular weight (550).
