m-PEG-Mal (MW 2000)（Cat No.:I045921）is a maleimide-activated polyethylene glycol derivative with a molecular weight of 2,000 Da. It is designed for selective conjugation to sulfhydryl groups, forming stable thioether bonds under mild physiological conditions. The PEG backbone enhances solubility, biocompatibility, and circulation half-life, while the maleimide group enables site-specific modification. This reagent is widely applied in preparing PEGylated proteins, peptides, antibodies, and nanoparticles. Its moderate chain length balances reduced immunogenicity with preserved bioactivity, making it valuable in drug delivery, targeted therapeutics, and surface functionalization research applications.
