Amine-PEG4-Amido-tri-(carboxyethoxymethyl)-methane is a branched PEG linker with an amine and three terminal carboxilic acid groups. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The terminal carboxylic acid groups can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
