3,4-Dibromo-Mal-PEG4-Amine is a site specific amine PEG linker with a dibromomaleimide group. The amino group (NH2) is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The dibromomaleimide group allows for two points of substitution due to the two bromine atoms. Dibromo-Maleimide is sensitive to high temperature and light.
