Lenti Non-Settled Suspension Harvest Clarification Process Development

This webcast features: Stephen Tottey, PhD, Associate Principal Scientist, Process and Technology Development, Wuxi Advanced Therapies and John Taylor, Process Development Scientist, MilliporeSigma. Clarification of non-settled Lenti suspension harvest can be challenging due to high level of impurities in the feed stream, physical characteristics of the vector, limited filter choices, and low recovery. A series of clarification studies led to the identification of two feasible clarification filter set up options that provide workable outcomes regarding product recovery, impurity reduction, process…

Manufacturing Considerations for Virus Filtration Processes Using Planova BioEX

This webcast features: Parag Patel, Senior Regional Manager, Asahi Kasei Bioprocess Viral clearance of biopharmaceutical- and plasma-derived therapeutics is an important regulatory requirement that ensures patient safety.  Although there are many viral clearance strategies and technologies that can be deployed, size exclusion filtration remains the gold standard in virus removal. Virus filtration by size exclusion is a robust method for removing virus without impacting the efficacy of the final drug product.  We will take you through the steps of developing…

A New AEX Mixed-Mode Chromatography Resin for High Selectivity and Recovery

This webcast features: Dr. Xuemei He, R&D Manager, Chromatography Media Chemistry, Bio-Rad Laboratories Biomolecules are becoming more diversified and complex. Bio-Rad’s newest hydrophobic AEX chromatography resin, Nuvia aPrime 4A, is engineered with distinct balance of ligand density and hydrophobicity. In this webinar, Dr. Xuemei He will introduce the properties of Nuvia aPrime 4A Resin. This mixed-mode resin is designed to facilitate selective and reversible binding of target molecules for higher purity and recovery over traditional chromatography resins. Case studies will…

Clearing the Way for Viral Clearance

This webcast features: David Cetlin, CEO, MockV Solutions and John Li, Staff Scientist, Thermo Fisher Scientific. To determine the viral clearance efficacy of biomanufacturing steps, mammalian viruses are “spiked” into in-process solutions, processed and analysed for reduction. Due to the infectious nature of these live viruses, “spiking studies” are typically conducted in specialized BSL-2 facilities. The costs and logistics associated limit viral clearance analysis during process development and characterization. To overcome this challenge, a non-infectious Minute Virus of Mice –…

Development of Affinity Chromatography Adsorbents for Bioseparations

This webcast features: Patrick Gurgel, Head of Research & Development, Prometic Bioseparations. Affinity chromatography has a long history of use in bioprocesses and is a powerful tool in making industrial processes more efficient by reducing the number of steps necessary to achieve the desired target purity and yield. It is common, however, for teams to only consider affinity chromatography as an alternative once other options have been considered, evaluated, and discarded, which translates into a need to develop affinity adsorbents…

From 1mL-100L: Consistent Chromatography Performance Across Multiple Sizes of Pre-Packed Columns

This webcast features: Fletcher Malcom, Product Line Leader, Repligen With the increasing use of pre-packed columns in protein separations, it is critical to demonstrate consistent chromatographic performance at different scales. This allows for seamless process scale-up and scale-down. This webinar will show how chromatography separation remains unchanged across different OPUS® Column sizes. Performance results obtained with bench-scale columns (≥1mL column volume) are demonstrated to be scalable to production sized columns (≤100L column volume). Just fill out the form below to…

Introducing Chromassette: Modular Chromatography Platform with a Lattice Supported Bed

This webcast features: Jason Chiu, Product Marketing Scientist, Bioprocess Group, JSR Life Sciences. Chromassette®, a lattice-supporting modular chromatography device, eliminates the constraints of modern column chromatography. The Chromassette technology offers the separation capabilities of conventional chromatography plus the convenience, scalability and other benefits of a pre-packed cassette through its unique, internal scaffold structure that provides consistent “wall support” to all resin beads. In this webinar we will discuss how Chromassette enables high flow-rates for any type of resin regardless of…

Dynamic Dialysis: A Novel Process-Scale Membrane Separation for GMP Manufacturing

This webcast features: Daniel (Danny) Spurgin, Product Manager, and Cassidy Markee, Bioprocess Sales Specialist, Repligen While static dialysis is used routinely in research and sample analysis, dynamic dialysis is increasingly used today for the purification of macromolecules, proteins, nanoparticles, biomolecules, polymers (polypeptides, polysacharide, oligos), virus for vaccine and delicate/shear sensitive species. It is also ideal for the purification of viscous fluids and hydrogels (hyaluronic acid – HA) that cannot be filtered. Where traditional filtration methods may fail, dynamic dialysis uses…

Minimizing Resources in Developing Commercial Virus Filtration Processes with Planova BioEX

This webcast features: Roya Dayani, Senior Product Manager, Asahi Kasei Bioprocess Europe Establishing a virus filtration step in biopharmaceutical development and manufacturing process may require a large amount of resources (i.e., time, manpower and cost). These can be minimized with swift process development, smooth scale-up and worry-free operations. In this webinar Asahi Kasei Bioprocess will answer the question “What are the main requirements for a virus filter at each phase?”. You will learn through different case studies the filtration performances…

New High Performance AEX Resin for Large Biomolecule Purification

This webcast features: Jiali Liao, Principal Scientist, Process Chromatography R&D, Bio-Rad Laboratories Large molecule purification can be difficult due to their size. This leads to slow diffusion and mass transfer kinetics of the molecules into the pores of traditional chromatography resins, which decreases their binding capacity and resolution. In this webinar, Dr. Jiali Liao will introduce the design features of the Nuvia HP-Q bead matrix that help overcome these purification challenges. Case studies on plasma protein and virus purification will…
