2.5× Lentiviral Vector Bioreactor Yield Increase and Simplified Execution with Innovative Tangential-Flow Depth Filtration

This webcast features: Michael Bransby, R&D Director of Process Technology, Repligen In a joint collaboration, Oxford Biomedica and Repligen increased the yield of viral vectors from suspension-cultured bioreactors several fold using tangential-flow depth filtration (TFDF). The yield for a single clarification step was 95% as compared to 70% by standard depth filtration. The TFDF tubular format and low shear enabled further yield increases through multiple harvests from the same seeding. A single seeded bioreactor produced two harvests of 95% and…

Protein A Chromatography: Using Automation Instead of Multiple Columns To Increase Productivity

This webcast features: Van Leang, Senior Director of Global CMC Operations, HJB Bio Vendors supporting biologics manufacturing are developing equipment to enable continuous process in downstream operations. Using continuous downstream operations reduces operational time and raw material costs. HJB has developed a downstream hybrid process that uses an automated batch approach to achieve a continuous downstream capture process. This allows the use of the current monoclonal antibody (MAb) capture platform but reduces cost overall by adopting the benefits of continuous…

Assessing Viral Clearance in Early Phase Process Development

This webcast features: William H. Rushton, Process Chromatography Support Scientist, Bio-Rad Laboratories Viral clearance studies are part of a multifaceted approach to ensure the safety of biopharmaceutical products. In order to prevent costly changes to a manufacturing process, it is important to assess each operation unit for its efficiency on the removal or inactivation of adventitious agents early on during downstream process development. A design of experiments (DOE) approach was utilized in this case study to investigate the effect of…

Accelerating Vaccine Development By Innovative Purification Solutions and State of the Art Quality Testing

This webcast features: Sirat Sikka and Florian Durst, Field Application Scientists (Purification and Pharma Analytics), Thermo Fisher Scientific The emergence of new diseases and infections has entailed the need for rapid and efficient development of safe and efficacious vaccines. Additionally, no effective vaccines currently exist for long-known pandemic diseases such as HIV or malaria. To address the challenges the vaccine industry faces, new vaccine modalities such as viral vectors, recombinant protein subunits, and nucleic acids are being researched and developed,…

Identification of Host Cell Protein (HCP) Impurities using Antibody Affinity Extraction and Mass Spectrometry Approach

This webcast features: Eric Bishop, Vice President of Research & Development, Cygnus Technologies A well-developed, broadly reactive, and qualified HCP ELISA remains a gold standard method effectively used during the purification process to ensure removal of HCP and to demonstrate process consistency and final drug substance purity. Unfortunately, the ELISA does not inform which HCPs are present or to which HCPs the assay reacts. Mass Spectrometry (MS) is a powerful tool for identifying those HCPs that persist through downstream purification…

Mixed-Mode Chromatography Resins​ for Biomolecule Purification

This webcast features: Dr. Xuemei He, R&D Chromatography Media Chemistry Manager, Bio-Rad Laboratories Mixed-mode chromatography has emerged as a viable purification method for biomolecules that are otherwise difficult to purify using traditional chromatography platforms and other established means. Scientists are gaining an increased understanding of mixed-mode mechanisms and how these interactions impact selectivity. The industry is becoming more adept at including mixed-mode steps in production processes while also working to address robustness, platform fit, and productivity. This webinar will examine…

Efficient Solutions for the Purification of Challenging Antibody Formats

This webcast features: Laurens Sierkstra, Senior Director, Business Leader, Purification, Thermo Fisher Scientific Inc., Bioproduction Leiden/Naarden, The Netherlands The changing landscape for antibody-derived therapeutics, such as bispecific monoclonal antibodies, Fab fragments, and Fc-fusion proteins brings new purification challenges in the downstream process of these molecules. Standard chromatography resins, such as Protein A, may not result in the most efficient process. Thermo Scientific™ CaptureSelect™ resins, focusing on alternative antibody domains, enhance the success of your antibody purification process. From research to…

Highly Sensitive Host Cell Protein Analysis Using µPAC™ LC-MS

This webcast features: Dr. Koen Sandra, Scientific Director, Research Institute for Chromatography Within a rapidly growing biopharmaceutical market, there is an increasing demand for the development of a rising number of biotherapeutic protein drugs, such as monoclonal antibodies (MAbs). During the development and production of biotherapeutic proteins, typically using mammalian cell lines, such as Chinese hamster ovary (CHO) cells, additional proteins are expressed as well by the host cell. These so-called host cell proteins (HCPs) will need to be removed,…
