HyNic-PEG2-Azide, The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. 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.
