A new alkyl maleimido activated monomethoxypoly(ethylene glycol) (PEG-C18-Mal) for site-directed protein conjugation was synthesised and characterized. As compared to the commercial mPEG-maleimido, PEG-C18-Mal was more efficient in the bioconjugation to 17Cys of rh-G-CSF in guanidinium free buffer and gave more stable bioconjugate. Also, the new bioconjugate displayed high biological activity.
