    Article Snippet: The COVID-19 pandemic has brought global attention towards the readiness of biotechnology platforms for rapid development of immunogens to be used as vaccine antigens, in diagnostics and in fundamental research.. In the present study we provide a bioprocess that is both robust and industry-compatible for high level expression, efficient purification, and scale-up of IMT-CVAX, a prefusion-stabilized trimeric spike protein of SARS-CoV-2.. The recombinant IMT-CVAX protein was produced using stable cell pool of Chinese Hamster Ovary (CHO-S) cells that were banked in compliance with cGMP (Current Good Manufacturing Practices) regulations.

    Article Title: rAAV expressing recombinant antibody for emergency prevention and long-term prophylaxis of COVID-19
    Article Snippet: The optimized sequence of the firefly luciferase gene Fluc was obtained from the vector pGL4.51[luc2/CMV/Neo] (Promega). .. Both sequences were cloned into the rAAV–EGFP Control Vector plasmid instead of the EGFP gene at the EcoRI and XbaI restriction sites, thus obtaining the rAAV-P2C5-Fc and rAAV-Luc plasmids, respectively. rAAV-P2C5-Fc and rAAV-Luc were produced by transient transfections of HEK293 cells (obtained from the cell cultures collection of the Gamaleya National Research Center for Epidemiology and Microbiology) and cultured in a BioFlo 320 bioreactor (Eppendorf, Germany) with a BioBLU 5c disposable vessel (Eppendorf, Germany) filled with Fibra-Cel matrix (Eppendorf, Germany). rAAV-P2C5-Fc and rAAV-Luc purification was performed using an AKTA flux S tangential flow filtration system (Cytiva Life Sciences, USA) and a Hollow Fiber Cartridge, 100 kDa (Cytiva Life Sciences, USA) following affinity chromatography using AVB Sepharose resin (Cytiva Life Sciences, USA) according to the manufacturer’s protocol. .. The purity of the obtained rAAV-P2C5-Fc and rAAV-Luc was assessed by SDS-PAGE with 4%−20% Mini-PROTEAN TG Precast Protein Gel (Bio-Rad, USA) under reducing conditions.
