Mal-PEG8-acid (Methoxy-polyethylene glycol-maleimide-carboxylic acid) is a heterobifunctional PEG reagent featuring a maleimide group for thiol conjugation and a terminal carboxyl group for amine coupling. This 8-unit PEG chain facilitates protein modification with improved solubility and reduced immunogenicity.
