bioCERTIFIED: Turn Your Quality Management System into a Competitive Advantage

This webcast features: Jigisha Patel, VP of Regulatory Compliance & Technical Services, Spectrum Chemical Mfg. Corp. What can go wrong will go wrong—unless you eliminate unpredictability that results in reworks, rising costs, nonconformance, and unreliable product performance. Learn how to implement quality management systems throughout your entire supply chain and help accelerate biopharmaceutical development and production time for first-mover advantages. Whether it’s upstream or downstream processing, you will gain new insight that enables you to eliminate unpredictability and batch-to-batch variability…

Ensuring Viral Safety in Cell & Gene Therapy Through Next-Generation Sequencing

by BPI Contributor

This webcast features: Horst Ruppach, Senior Scientific and Portfolio Director, Global Biologics, Charles River The viral contamination risk of cell and gene therapy products is significant. Multiple factors open the windows for viruses to enter the process. The current viral risk mitigation strategies have limitations and can either not be applied or have limitations to cover a broader range of potential viral contaminants. One of the most important entry points to monitor are the cells. They are used to produce…

Key Considerations for Maximizing LV and AAV Production in Transient Transfection Workflows

by BPI Contributor

This webcast features: Leisha Kopp, Applications Scientist, Mirus Bio Recombinant adenoassociated virus (AAV) and lentivirus (LV) are critical components of gene and cell therapies, which show incredible promise for the treatment of disease. Accordingly, the need for large-scale manufacture of safe and effective viral vectors has never been greater. Here, we present: Optimization strategies for AAV and LV generation in both adherent and suspension HEK 293 cells LV and AAV enhancers that further increase functional virus titers over previously optimized…

“Breez”ing the Way into Process Development with Perfusion Technology

by BPI Contributor

This webcast features: Kevin Lee, Co-Founder, Principal Scientist, Erbi Biosystems The priority of speed to market is often at odds with issues around development resources, facility space, and infrastructure for both development and manufacturing. Continuous bioprocessing provides solutions for many of these challenges in certain applications, but to deliver on this promise we need fit-for-purpose tools and technologies to enable process development and provide reliable transfer to commercial manufacturing. The migration to continuous processes in process development is further hindered…

Automation of a Next-Generation Sequencing Method for Cell Line Species Identity

by BPI Contributor

This webcast features: Dr. Christine Mitchell, Scientific Fellow, Analytical Development, WuXi Advanced Therapies As the gene and cell therapy market continues to expand, affordability and accelerated turnaround time (TAT) become increasingly important in the industry. Despite the escalating diversity of therapeutic modalities, the criticality of a robust cell bank remains a pivotal starting point for many biological products. The integrity of species identity for cell lines is a critical quality attribute for many cell and gene therapies, and with regulatory…

Ask the Expert: High-Yield mRNA Processing — From Plasmid to Highly Purified Product

by BPI Contributor

Interest in industrial-scale production of messenger RNA (mRNA) has surged amid rapid development of mRNA-based vaccines against SARS-CoV-2. During an 18 February 2021 Ask the Expert presentation, Aleš Štrancar (chief executive officer of BIA Separations, a Sartorius company) reminded attendees that no platform approach yet exists for mRNA production and that much remains to be learned about manufacturing such products at commercial scales. He described current production challenges and shared BIA’s efforts to devise flexible mRNA purification tools. Štrancar’s Presentation…

Ask the Expert: Leveraging Cloud Capabilities to Execute CHO Cell Culture Experiments

by BPI Contributor

Process development teams have relied for decades on benchtop bioreactors to perform mammalian-cell–culture experiments; however, doing so requires significant resources and staffing. During a 24 February 2021 presentation, Deborah Pascoe, PhD, vice president of operations at Culture Biosciences (Culture), explained how to leverage her company’s high-throughput, cloud-connected bioreactors to execute Chinese hamster ovary (CHO) cell cultures with high reproducibility and scalability. Pascoe’s Presentation Pascoe described her company as an extension of a customer’s laboratory. After technology transfer, Culture and a…

Virus-Like Particle Production in Insect Cells Using the Baculovirus Expression System: Addressing Challenges across the Workflow

by BPI Contributor

This webcast features: Maya Yovcheva, R&D Scientist, Cell Biology, Chantelle Gaskin, Field Applications Scientist, Purification, and Florian Durst, Sr. Field Application Specialist, Pharma Analytics, Thermo Fisher Scientific Being part of the newer generation of vaccines, virus-like particles (VLPs) have proven to be effective in humans as well as animals. VLPs mimic the structure of the virus particles they are derived from and are highly immunogenic, but they lack the virus genomic material which gives them a favorable safety profile. The…

Manufacturing a Recombinant Retrovirus: Downstream Purification Process Development through GMP Implementation

by BPI Contributor

This webcast features: Mark Fitchmun, President and CEO, Somatek, Inc. Purification of enveloped viruses and virus-like particles presents several challenges due to their large size and complexity. In this webinar, a case study will be presented and will detail the importance of resin screening, endonuclease treatment, process development, and the scale-up purification of a retrovirus-like particle intended for use in human subjects. The resulting current good manufacturing practice (CGMP) compatible process required approximately four hours to purify 240 L of…

Increase Efficiency in Your Manufacturing With the Right Buffer Management Strategy

by BPI Contributor

This webcast features: Jenny Dunker, Global Product Manager, and Alex Troken, Global Product Manager, Cytiva Buffer preparation is still a highly manual activity in the biopharmaceutical industry that often requires a lot of resources due to the large number and overall volume of buffers and process liquids used in a typical bioprocess workflow. Most companies are still relying on the traditional ways of preparing buffers, but there are more modern, alternative buffer preparation methods that can bring significant savings and…
