抄録

  Diphenyl 1-amino-2-phenylethylphosphonate was introduced to poly(ethylene glycol)s (PEGs) with average molecular masses of 300, 400, and 600 to prepare water-insoluble PEG-inhibitor conjugates. Interestingly, only the conjugate from PEG with an average molecular weight of 600 formed a precipitate with chymotrypsin but not with trypsin. The results demonstrated that the PEG-inhibitor conjugate is useful for separation of chymotrypsin.<br>
