Lab-scale production of anti-Schistosoma monoclonal antibodies by hybridoma culturing in serum free medium: Enhancement of growth, cryopreservation survival rate, and diagnostic accuracy. Exp Parasitol 2022; 242:108390. [PMID: 36179853 DOI: 10.1016/j.exppara.2022.108390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 09/18/2022] [Accepted: 09/23/2022] [Indexed: 11/15/2022]
Abstract
This study was performed to evaluate the effect of two commercially available serum-free culture media; serum free medium (SFM) and chemically defined medium (CDM), on the growth rate, antibody productivity and post adaptation cryopreservation and revival reactivity of hybridoma cells compared to the conventional serum based medium (SBM). In addition, the diagnostic efficacy of MAbs secreted in each culture medium was evaluated by testing their performance in sandwich ELISA for antigen detection. Anti- Schistosoma mansoni soluble egg antigen hybridoma cell line (7A/8F) secreting previously characterized IgG Kappa mAbs, were retrieved and propagated in each of the three aforementioned media. Growth rate and viability were assessed post culturing in each media. The data collected from this study indicated that MAbs secreted from hybridoma cells cultured in SFM were the most abundant, easiest to purify, and the most effective in antigen detection by sandwich ELISA, in comparison to those produced in the other two media. Moreover, combination of fresh and conditioned medium with DMSO 7.5% was the most promising formulation for the cryopreservation of hybridoma cells cultivated in serum independent media (SFM or CDM).

Abstract
Monoclonal antibodies are widely used as diagnostic reagents and for therapeutic purposes, and their demand is increasing extensively. To produce these proteins in sufficient quantities for commercial use, it is necessary to raise the output by scaling up the production processes. This review describes recent trends in high-density cell culture systems established for monoclonal antibody production that are excellent methods to scale up from the lab-scale cell culture. Among the reactors, hollow fiber bioreactors contribute to a major part of high-density cell culture as they can provide a tremendous amount of surface area in a small volume for cell growth. As an alternative to hollow fiber reactors, a novel disposable bioreactor has been developed, which consists of a polymer-based supermacroporous material, cryogel, as a matrix for cell growth. Packed bed systems and disposable wave bioreactors have also been introduced for high cell density culture. These developments in high-density cell culture systems have led to the monoclonal antibody production in an economically favourable manner and made monoclonal antibodies one of the dominant therapeutic and diagnostic proteins in biopharmaceutical industry.

Semliki Forest Virus replicon particles production in serum-free medium BHK-21 cell cultures and their use to express different proteins. Cytotechnology 2019; 71:949-962. [PMID: 31422494 DOI: 10.1007/s10616-019-00337-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Accepted: 08/13/2019] [Indexed: 12/12/2022] Open
Abstract
The production of biopharmaceuticals as vaccines in serum-free media results in reduced risk of contamination and simpler downstream processing. The production of enveloped viruses and viral vectors such as Semliki Forest Virus (SFV) typically requires lipids that are provided by supplementation with animal serum, so production under serum-free conditions is challenging. In this work, the capacity to deliver genetic material of SFV-viral replicon particles (SFV-VRPs) produced in BHK-21 cells adapted to serum-free medium (BHK/SFM) was evaluated. Three transgenes were evaluated: GFP used as a model protein, while hepatitis C virus nonstructural protein 3 protease domain (HCV-NS3p) and rabies virus glycoprotein (RVGP) were selected based on their distinct nature (enzyme and glycoprotein, respectively). BHK/SFM cells produced a sevenfold higher number of SFV-VRPs, as determined by qRT-PCR. These particles showed similar capacities of infecting BHK/FBS or BHK/SFM cells. GFP expression was evaluated by flow cytometry, HCV-NS3p activity by enzymatic assay, and RVGP expression by ELISA and Western Blot. Expression analysis revealed higher levels of GFP and HCV-NS3p in BHK/SFM, while the levels of RVGP were similar for BHK/SFM and BHK/FBS. In conclusion, the BHK/SFM cells showed increased SFV-VRP production yields, without affecting vector infectivity or heterologous gene expression, hence validating the use of BHK/SFM for industrial applications.

Abstract
Most bio-industrial mammalian cells are cultured in serum-free media to achieve advantages, such as batch consistency, suspended growth, and simplified purification. The successful development of a serum-free medium could contribute to a reduction in the experimental variation, enhance cell productivity, and facilitate biopharmaceuticals production using the cell culture process. Commercial serum-free media are also becoming more and more popular. However, the cell line secrets its own recombinant product and has special nutritional requirements. How can the composition of the proprietary medium be adjusted to support the specific cell's metabolism and recombinant protein? This article uses statistical strategies to modify the commercial medium. A design of experiments is adopted to optimize the medium composition for the hybridoma cell in a serum-free condition. The supplements of peptone, ferric citrate, and trace elements were chosen to study their impact on hybridoma growth and antibody production using the response surface methodology. The stimulatory effect of the developed formulation on hybridoma growth was confirmed by the steepest ascent path. The optimal medium stimulated the hybridoma growth and antibody production in three diverse systems: a static plate, an agitated spinner flask, and a hollow fiber reactor. The cells in the developed serum-free medium had a better antibody production as compared to that in the commercial medium in the hollow fiber reactor. Our results demonstrated that the facile optimization for medium and antibody production was successfully accomplished in the hybridoma cells.

Abstract
Macrophage-conditioned medium (MCM) is an important cell culture supplement used to support the survival and growth of newly fused hybridoma cells. The use of macrophage cells, as a part of hybridoma technology, has proven to be an effective and inexpensive source of growth factors that promote the early survival and growth of hybridoma cells. Despite the widespread use of MCM as a hybridoma culture supplement, there is limited guidance and standardization for MCM production to achieve optimal hybridoma support. As an undefined supplement, significant variations in production of MCM may negatively impact hybridoma cell survival and growth. The lack of an available method for standardization of MCM bioactivity has limited validation, optimization, and commercial production. Consequently, variations in batch production of MCM may result in low-quality MCM that limits hybridoma viability and negatively impacts monoclonal antibody production. In this report, we describe a novel bioassay based on the newly generated, MCM-dependent RMH359 hybridoma cell line that can be used to validate MCM bioactivity and standardize production. We demonstrate the utility of the RMH359 bioassay (1) for evaluating MCM hybridoma bioactivity, (2) to define optimal conditions for production of MCM, and (3) as a method for MCM validation and standardization. In conclusion, the RMH359 cell bioassay provides a specific and sensitive assessment of MCM bioactivity in support of hybridoma cell survival and growth.

Abstract
With the recent outbreaks of Zika and Dengue virus infections in various countries worldwide, production of vaccines or diagnostic kits is an urgent public health demand. Production of a monoclonal antibody (mAb) that specifically binds to a common antigen shared by the Flavivirus genus will be necessary for new diagnostic kits or characterization and viral identity tests during vaccine development. This study aimed to cultivate, in serum-free conditions, the 4G2 hybridoma that produces an mAb, which recognizes a shared epitope from the Flavivirus genus. We compared 4G2 hybridoma growth and biochemical profiles between cells cultivated in batch mode over 10 days in roller bottles containing Dulbecco's modified Eagle's medium high glucose containing 10% fetal bovine serum medium or hybridomas directly adapted to Ex-Cell serum-free medium. Cellular parameters such as specific growth rate (μ), maximum cell concentration, specific l-lactate, and glucose and IgG rates were evaluated. Thereafter, we also compared total mAb volumetric productivity, purification yield, and mAb staining of Vero cells infected with Zika and Dengue-2 virus. Direct adaptation to serum-free conditions did not change hybridoma growth rate and mAb production under the conditions tested. Instead, serum-free mAb purification showed a higher yield with no alterations on mAb structure or mAb staining of Zika and Dengue Vero-infected cells.
