Determination of the optimal method for the concentration and purification of 146S particles for foot-and-mouth disease vaccine production. J Virol Methods 2019; 269:26-29. [PMID: 30974178 DOI: 10.1016/j.jviromet.2019.04.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2018] [Revised: 02/15/2019] [Accepted: 04/07/2019] [Indexed: 02/04/2023]
Abstract
After the severe outbreak of foot-and-mouth disease (FMD) in South Korea in 2010, the Korean government implemented a vaccination policy and set out to develop an FMD vaccine using a local FMD virus (FMDV) strain. As a part of the basic research for domestic FMD vaccine development, three methods commonly used for the concentration and purification of FMDV to produce FMD vaccine antigens were compared. Among common concentration methods, including polyethylene glycol (PEG) precipitation, ammonium sulfate precipitation, and ultrafiltration, the most effective method both for concentrating 146S particles and eliminating non-structural proteins (NSPs) was found to be PEG precipitation. Classical PEG precipitation showed the highest recovery of 146S particles (85.4%) with removing 99.8% of the other proteins, including NSPs. To the author's knowledge, this is the first study to compare the current three methods with regard to quantifying intact virus particles (146S). These findings may provide important insights for the development of new FMD vaccines using a local FMDV strain in the near future.

Brilliant Blue Dyes in Daily Food: How Could Purinergic System Be Affected? INTERNATIONAL JOURNAL OF FOOD SCIENCE 2016; 2016:7548498. [PMID: 27833914 PMCID: PMC5090090 DOI: 10.1155/2016/7548498] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/31/2016] [Accepted: 08/28/2016] [Indexed: 11/21/2022]
Abstract
Dyes were first obtained from the extraction of plant sources in the Neolithic period to produce dyed clothes. At the beginning of the 19th century, synthetic dyes were produced to color clothes on a large scale. Other applications for synthetic dyes include the pharmaceutical and food industries, which are important interference factors in our lives and health. Herein, we analyzed the possible implications of some dyes that are already described as antagonists of purinergic receptors, including special Brilliant Blue G and its derivative FD&C Blue No. 1. Purinergic receptor family is widely expressed in the body and is critical to relate to much cellular homeostasis maintenance as well as inflammation and cell death. In this review, we discuss previous studies and show purinergic signaling as an important issue to be aware of in food additives development and their correlations with the physiological functions.

Abstract
Rubella is a highly contagious viral disease which is mostly threatens to women of reproductive age. Existent live attenuated vaccines are effective enough, but have some drawbacks and are unusable for a certain group of people, including pregnant women and people with AIDS and other immunodeficiency. Thereby the development of alternative non-replicating, recombinant vaccines undoubtedly is needed. This review discusses the protein E1 and E2 role in formation of immune response and perspectives in development of new generation recombinant vaccines using them.

Abstract
Rapid expression of recombinant proteins for structure determination is one of the major challenges in pharmaceutical and academic research, since the number of potential drug targets has increased significantly in the last decade. Despite the fact that the baculovirus expression vector system is widely used for this purpose, the system is hampered by three very slow and tedious procedures, namely generation of high titer baculovirus stock, determination of the virus titer and discovery of the best conditions for protein expression. We herein describe the development of the ultraBac system to address and overcome these issues for protein expression in insect cells. We have established a new baculovirus expression technology for insect cells that is based on co-expression of GFP with target genes, a new regime for cell culturing and a highly efficient purification and enrichment procedure for recombinant baculovirus particles. Co-expression of GFP is used to monitor the infection of insect cells, to simplify titer determination and to optimize expression conditions. The new regime for cell culturing with increased viability of non-infected insect cells and its combination with the massive enrichment of virus particles via high-speed centrifugation enables the production of large amounts of recombinant virus in a very short period of time. By combining these techniques and by using the bicistronic vector pUltraBac-1, we have been able to cut the time-lines for protein expression in insect cells by half, approaching those for protein production in Escherichia coli. This new expression system is a significant step forward towards industrialized protein production in both, industry and academia.

Abstract
Stably transfected Chinese hamster ovary (CHO24S) cells were the source for Rubella virus-like particles (RVLP) containing all structural proteins (E1, E2, C and their dimers). RVLP are secreted from the CHO24S cells into the medium and the time-point for collecting the medium with the highest yield of >100 kDa proteins (with 17 mg protein from 10 ml cell culture supernatant) was after 2 days of incubation. Different methods for RVLP isolation from the cell culture supernatants were assessed by SDS-PAGE and Western blotting (using sera positive or negative for Rubella virus (RV)-specific antibodies or an anti-E1 monoclonal antibody). A combination of membrane filtration with a rapid, novel gradient ultracentrifugation step (using Coomassie brilliant blue G crystals as adsorbens for RVLP that facilitated virus isolation) was the most suitable technique. 132 RV-positive human sera (RV IgG > 20 IU/ml by commercial ELISA) were tested by our "self made" immunoblot test stripes (using RVLP adsorbed to dye crystals as antigen) for the presence or absence of antibodies specific for RV structural proteins. 57.6% of these sera had antibodies against E1, E2 and C, 31% against E1 and C, and 1.5% against E1 only, whereas 3.8% had no RV specific antibodies and only 6.0% were equivocal which demonstrated that these "self made" test stripes can reliably differentiate RV antibody specificities.
