英文摘要 | in this study, we described a simple and effective modification procedure to prepare poly (methacrylate-co-ethylene glycol dimethacrylate) monolithic columns functionalized with 3-aminophenylboronic acid. the column morphology, pore size and specific surface area of the fabricated monolith were characterized by scanning electron microscopy, x-ray photoelectron spectroscopy, thermogravimetric analysis, and mercury intrusion porosimeter, respectively. the frontal analysis was carried out for dynamic loading capacity of the model protein on the modified column. the chromatographic performance of the cation-exchange monolith was evaluated through separating a mixture of five proteins such as lysozyme, cytochrome c, ribonuclease a, trypsin and bovine serum albumin and one-step purification of lysozyme from egg whites, and the expected results were obtained. in addition, the functionalized column was used to refold ribonuclease a and cytochrome c. and this procedure was monitored by circular dichroism and fluorescence spectroscopy. compared with the conventional dilution refolding method, the ion-exchange chromatography refolding method developed here is more effective for specific bioactivity recovery.
