It is a useful crosslinking reagent with a PEG spacer. Maleimide reacts with thiol, SH, sulfhydryl or mercapto, and amine can react with carboxylic acid or activated NHS ester. MAL-PEG-NH2 can also be used to synthesize PEGylated block copolymers such as PEG-PLL (poly-L-lysine) and PEG-PLGA (poly-L-glutaric acid). It is typically provided as a TFA or HCl salt. Maleimide contains a reactive C=C double bond and is light or oxygen sensitive.; 6) 规格: 100mg 甄准免费
