4-Arm-PEG-Maleimide (MW 2000)

4-Arm-PEG-Maleimide (MW 2000) (4-Arm-PEG-Mal (MW 2000)) is a PEG derivative modified with Maleimide (HY-W007324), which forms a stable thioether bond with sulfhydryl (-SH). PEG modification can improve solubility and stability and reduce the immunogenicity of proteins and peptides.
