Boc-HyNic-PEG1-Mal, The maleimide group reacts specifically with a thiol group to form a covalent C-S bond, enabling the bioconjugation with a thiol bearing molecules.The HyNic hydrzine moiety easily conjugate with aldehyde group and ketone group to form a reversible hydrazone linker, making it an ideal tool for carbonyl labelling. The PEG spacer increase the solubility of the resulting complex in aqueous media.
