Accelerating Discoveries for Viral Biology and Host Immunity with Advanced Cell Analysis Solutions

This whitepaper summaries recently published studies that incorporated the Incucyte® Live-Cell analysis platform and iQue® 3 Advanced High-Throughput Flow Cytometry. These state-of-the-art technologies were used to simplify workflows and provide rapid analysis solutions and enhanced throughput, aiding the discovery of new insights on the host-pathogen life cycle throughout the course of infection. Post-infection, these platforms were leveraged to monitor exposure, assess immune protection, and accelerate the development of anti-viral small molecules, neutralizing antibodies, and vaccines. The Incucyte® platform offers automated…

Using Bio-Layer Interferometry for A Fast and High Precision Influenza Vaccine Potency Assay

A fast and accurate determination of vaccine titer during manufacturing is important in understanding vaccine development process performance, and for correctly scaling each process step. The Single Radial Immunodiffusion (SRID) technique has been the most commonly used technique for vaccine titer determination. However, SRID is time consuming and generally exhibits poor precision. An alternative assay that can speed up the analysis process and provide accurate and precise potency data on different vaccine strains is therefore desirable. The Octet® platform’s Bio-Layer…

Cell Line Development: Accelerating Process Optimization by Combining Ambr® 15 Cell Culture with Octet® Titer Measurements

Cell line development (CLD) involves the screening of thousands of clones to find those that are stable, produce high yields of the bioproduct and exhibit desired critical quality attributes (CQAs). Typically screening and process optimization activities will be carried out at the small scale in bioreactor cultures to ensure that results translate up to larger bioreactor scales. Performance data is primarily based on cell growth, cell viability, metabolite analysis and product titer, and assessed over the entire culture process duration.…

The Importance of Raw Materials in Viral Vector Manufacturing

Focus on transfection reagent. The rapid advance of so many gene therapy candidates is creating several key challenges. There is a strong need for higher viral vector yields and scalable manufacturing to reduce costs of gene therapy for affordable patient treatment, all of that while meeting cGMP compliance to ensure patient safety which, push comes to shoves, always comes first. A critical step for viral vector manufacturing is sourcing of raw materials to maximize production yield while meeting quality requirement.…

Guidelines for Developing a High Cell Density Cryopreservation Process

Biopharmaceutical manufacturers are leveraging several approaches to intensify processes with a goal of improving efficiency and productivity and reducing costs — all while ensuring the highest quality standards. The upstream workflow offers several opportunities to apply next generation technologies and methods to achieve these important goals. In this white paper we discuss integration of high cell density cryopreservation (HCDC) in the seed train and explore key considerations for developing a cryopreservation process including choice of cryoprotectant and freezing techniques.

How to Find Expression and Purification Conditions That Result in High Levels of Thermally Stable Membrane Proteins

It’s very common to experience low expression levels when producing membrane proteins — plus they’re finicky and unstable when they’re outside of their native environment. Just know, you’re not alone. In this webinar, we’ll introduce you to the latest technology and techniques that will help you: More easily find the best expression and purification conditions that yield properly folded membrane proteins, saving you time and resources in producing membrane proteins that are stable and functional for downstream use Characterize the…

Media Management: A Critical Consideration Before Intensification

Process intensification (PI) enables faster drug development and increased productivity, flexibility, and quality. But PI can also introduce the challenge of increased media volumes and how to manage them in upstream processes. This whitepaper provides the tools and information needed to consider PI options while evaluating the implications of media management. Follow the media journey from prep to use, exploring potential logistical pitfalls in managing increased media volumes associated with process intensification. Finally, see how the right equipment and platforms…
