4-Arm-PEG-Maleimide (MW 400)

4-Arm-PEG-Maleimide (MW 400) (4-Arm-PEG-Mal (MW 400) ) is a PEG derivative modified with Maleimide , which forms a stable thioether bond with sulfhydryl (-SH). PEG modification can improve solubility and stability and reduce the immunogenicity of proteins and peptides[1].
