Mal-amido-PEG11-amine TFA salt linker contains a maleimide group and an amine group. The PEG spacer increases the aqueous solubility of the resulting compound. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The maleimide group reacts specifically with thiol groups to form a covalent C-S bond, enabling bioconjugation with thiol bearing molecules.
