Hydroxy-PEG3-acrylate linker contains a hydroxyl group and an acrylate group. The hydroxyl group can be derivatized to other reactive functional groups for conjugation. The acrylate group easily reacts with cystein thiols to form a S-C bond through Michael addition. The PEG spacer increases the aqueous solubility of the resulting compound.
