mPEG-Mal (MW 5000) is a PEG-derived selective covalent binding agent targeting sulfhydryl groups, facilitating irreversible thioether bond formation under near-neutral conditions. This reagent serves dual roles: as an enzyme modifier, it alters protein secondary structures through interactions such as hydrophobicity and hydrogen bonding, and as a nanoparticle surface modifier, it enhances macrophage phagocytosis by covalently binding to red blood cell surface sulfhydryl groups. mPEG-Mal (MW 5000) increases the apparent molecular weight of modified proteins, bolsters enzyme thermal stability and activity, and enhances nanoparticle targeting in drug delivery. Its applications extend to enzyme engineering in the food industry and oncology research, contributing to improved radiotherapy outcomes by modulating macrophage infiltration and anti-tumor immune responses.
