lentiviral vector aex Tridgett and colleagues describe the development of packaging and producer cell lines for lentiviral vector manufacture for cell and gene therapies. These reduce or eliminate the requirement for plasmid transfection, while remaining as productive as the industry-standard procedure. By bringing costs down, patients’ access to . Certainly, AEX is the preferred ion-exchange technique used for LV. Where AEX is not used, and capture is performed using TFF, multi-modal chromatography using CaptoCore from Cytiva (in flow-through mode) has seen promising results for impurity removal in lentiviral vector processes (James et al. 2016; Do Minh and Kamen 2021). . Introduction. Lentiviral vectors (LVs) have become the benchmark for ex vivo gene and cell therapy applications due to their ability to efficiently and permanently integrate in the host cell genome with low risk of genotoxicity. 1, 2 In particular, LV-based gene therapy and precise gene editing in hematopoietic stem/progenitor cells (HSPCs) . The final infectious titer of the lentiviral vector product manufactured using the optimized scale-up process was determined to be 1.97 × 10 9 transducing units (TU) . Anion exchange (AEX) 15 and affinity chromatography 16 have been suggested for the main purification step and size-exclusion chromatography for a polishing step. 14 However, .step that has been the bottleneck in lentiviral vector purifica-tion scale-up.

lentiviral vector aex Lentiviral vectors (LVs) are powerful gene-transfer tools routinely exploited for distinct research and clinical applications. LVs produced in most research laboratories contain contaminants that can generate confounding effects in experimental studies. Soldi et al. describe a laboratory-scale workflow for purified LV production, highlighting . The use of viral vectors as therapeutic products for multiple applications such as vaccines, cancer treatment, or gene therapies, has been growing exponentially. Therefore, improved manufacturing processes are needed to cope with the high number of functional particles required for clinical trials and, eventually, commercialization. Affinity . The demand for Lentiviral Vector (LV) drug substance is increasing. However, primary capture using convective anion-exchange chromatography remains a significant manufacturing challenge. This stems from a poor understanding of the complex adsorption behaviors linked to LVs intricate and variable structure, such as high binding . 1. Introduction. Lentiviral vectors (LVs), a complex subclass of the Retroviridae family, have emerged as one of the most used delivering tools in cell and gene therapy [].The increasing interest in LVs is mostly related to their ability to transduce proliferating and non-proliferating cells [], to integrate and deliver long-term gene .
