- Alternative purification method for recombinant measles viral nucleoprotein expressed in insect cells by ion-exchange chromatography.
- Lee HS1, Kim YJ1, Yang J1, Yoon HS1, Kim ST1, Kim K2.Author information 1Division of Respiratory Viruses, Center for Infectious Diseases, National Institute of Health, Korea CDC, Osong Health Technology Administration Complex, Cheongwon-gun, Chungbuk 363-951, South Korea.2Division of Respiratory Viruses, Center for Infectious Diseases, National Institute of Health, Korea CDC, Osong Health Technology Administration Complex, Cheongwon-gun, Chungbuk 363-951, South Korea. Electronic address: tigerkis@gmail.com.AbstractRecombinant measles virus nucleoproteins (rMeV N) and fusion (F) proteins were characterized as major antigenic proteins expressed in insect cells mediated by recombinant baculoviruses (rBVs). Band intensities were analyzed by Western blotting to recognize IgG and IgM antibodies against the rMeV N and F proteins in human sera and cerebrospinal fluids (CSFs) from patients with measles infections. Positive results from the blots using the rMeV N were consistent with the results of enzyme-linked immunosorbent assays (ELISAs) in which whole viral proteins were used as antigens. Human sera and CSFs reacted more strongly with the rMeV N than with the rMeV F proteins prepared in an identical expression system. For efficient and reliable purification, ion-exchange chromatography using Source Q anion resin was applied, and high-purity rMeV N protein was harvested. To characterize the similarity with the native viral protein to purified N protein, structural mimicry of purified recombinant proteins with intact rMeV N was shown through transmission electron microscopy, and the truncation and the phosphorylation status of the expressed protein were analyzed. These results suggest that the rMeV N purified by ion-exchange chromatography has features similar to those of naïve N including a self-assembled structure, phosphorylation and antigenic function. Thus, these expression and purification methods can be applied to the large-scale production of the rMeV N, which is essential for the development of new diagnostic tools and vaccines for acute and chronic MeV infections.

- Autonomous, waste-free eluent generation and suppression in a single device: Electrodialytic eluent reflux for ion chromatography.
- Elkin KR1, Riviello JM2.Author information 1Norwegian University of Life Sciences, Institute for Plant and Environmental Science, 1432 Ås, Norway. Electronic address: kyle.elkin@umb.no.2Trovion Company, Campbell, CA 95008, United States *Corresponding author. E-mail address: kyle.elkin@umb.no(K.R. Elkin).AbstractEluent reflux provides a new approach to suppress and reflux (recover) eluent without the continuous generation of chromatographic waste. The current work utilized a device containing ion exchange membranes at the electrodes, in order to prohibit electrolysis gases from entering the eluent stream. Two resin beds (separated by a membrane stack) were responsible for suppressing incoming eluent and regenerating the suppressed eluent to nearly its original concentration after detection. A greater than expected dilution in the eluent concentration was observed as a result of the minor leakage of potassium ions through the anion membrane stack into the electrode chamber. The incomplete recovery of the eluent was offset by the addition of a three port valve (DRV) to regulate eluent concentration. Over 48h of continuous operation (192 injections), the device's performance was stable (RSD of 0.21% with the three port valve, compared to RSD 3.73% without). The device was able to operate for up to four weeks using 1L of eluent. Chromatograms showing the reproducibility of the device are presented for anions.

- Adsorption of polyethylene-glycolated bovine serum albumin on macroporous and polymer-grafted anion exchangers.
- Zhu M1, Carta G2.Author information 1Department of Chemical Engineering, University of Virginia, Charlottesville, VA 22904, USA.2Department of Chemical Engineering, University of Virginia, Charlottesville, VA 22904, USA. Electronic address: gc@virginia.edu.AbstractThe chromatographic and adsorptive properties of BSA and BSA conjugated with 10 and 30kDa PEG polymers are determined for a macroporous anion exchanger (UNOsphere™ Diol Q) and for a polymer-grafted material having the same backbone matrix (Nuvia Q™). Chromatographic retention, adsorption capacity, and adsorption kinetics are enhanced in the polymer-grafted resin for both BSA and 10kDa PEG-BSA as a result of interactions with the grafted polymers. However, the difference between the two resins diminishes for 30kDa PEG-BSA indicating that size exclusion effects strongly affect binding in the polymer-grafted material for this larger conjugate. Images of intraparticle concentration profiles obtained by confocal scanning laser microscopy show that the transport mechanisms of both BSA and PEGylated BSA are very different in the two resins. The protein binding kinetics are dominated by ordinary pore diffusion and are essentially independent of the direction of transport for UNOsphere Diol Q as a result of its large pore size. Thus, for this material, displacement of PEGylated BSA by BSA is clearly evident at the intraparticle scale. On the other hand, the protein binding kinetics in Nuvia Q are consistent with a solid diffusion mechanism driven by the adsorbed protein concentration. For this material, protein transport is very fast for one component or two-component co-adsorption of BSA and PEGylated BSA but slows down dramatically for sequential adsorption of these species as a result of heightened diffusional hindrance when the two components counterdiffuse within the resin.
