Mal-PEG2-NH-Boc linker contains a maleimide group and a Boc protected amine group. The PEG spacer increases the aqueous solubility of the resulting compound. The protected amine can be deprotected by acidic conditions. The maleimide group reacts specifically with a thiol group to form a covalent C-S bond, enabling the bioconjugation with a thiol bearing molecules.
