dc.description.abstract | Chelex 100 is a highly effective adsorbent for the separation of metal ions from proteins for three reasons: (i) it has a high affinity for metal ions; (ii) proteins with molecular weight of 1000 or higher are excluded from the particle pores; and (iii) it also allows high flow rates, because it can withstand a pressure drop up to 100 psi. In this study, a carousel process based on Chelex 100 has been developed for the removal of Zn ions from protein in a buffer solution. The intrinsic parameters for the carousel design were estimated from a series of single-column experiments, which showed that Chelex 100 has a high selectivity for Zn ions in I N acetic acid and it can be effectively regenerated using 0.1 N HCl. The exchange mechanisms between Zn2+ and H+ on Chelex 100 were studied and considered in rate model simulations. The effective zinc isotherm was determined to be unfavorable in 1 N acetic acid. A design method based on the standing wave analysis for unfavorable isotherm systems has been developed in this study to ensure high product purity and high yield in carousel ion-exchange processes. Computer simulations and several laboratory-scale carousel experiments showed that the design method and the proposed carousel process can achieve high product purity (100%) and high product yield (> 99%). Compared to a batch size-exclusion chromatography process described previously [Xie et al., Biotechnol. Prog. 2002, 18, 1332], a three-zone carousel process that was based on Chelex 100 has more than 600 times the throughput per bed volume, requires only 63% of the mobile phase, and has a smaller residence time (by a factor of 50). | - |
