Description

MAL-PEG-OH (Maleimide-PEG-Hydroxy, Maleimide-PEG-OH) is a linear heterobifunctional PEG reagent with a maleimide and a hydroxyl group. It is a useful crosslinking reagent with a PEG spacer. Maleimide reacts with thiol, SH, sulfhydryl or mercapto. Hydroxyl can react with carboxylic acid. MAL-PEG-OH is useful to synthesize PEGylated block copolymer such as PLA-PEG (poly-L-lactic acid-co-polyethylene glycol) and PCL-PEG (polycaprolactone-co-polyethylene glycol) through hydroxyl initiated polymerization with lactide or caprolactone. Maleimide contains a reactive C=C double bond and is light or oxygen sensitive. MAL-PEG-OH may be also useful as a monofunctional maleimide PEG as an alternative to mPEG-Maleimide. Hydroxyl-terminated PEG has reported to have different immune responses compared to methoxy-terminated mPEG-Maleimide.
