Scalable Purification Strategies for Viral Vectors and Vaccines

Large-scale downstream processing of viruses can face a range of obstacles different from those of many biotherapeutics. These challenges mostly arise from the size and complexity of the virus, which can affect product purity and recovery. Improvements of purification tools are necessary to overcome these challenges and must be engineered for easy scalability to meet manufacturing demands. In this video, Dr. Mark Snyder discusses common difficulties when developing purification strategies for vaccine production and gene therapy.

What You Need to Know About Packing Resins at Process Scale

Learn best practices and guidelines for successfully packing different types of chromatography resins in this video webinar. This includes incompressible resins, like CHT Ceramic Hydroxyapatite Media, as well as traditional compressible resins. In general, parameters such as compression factor, settling rate, and attributes of the base matrix need to be considered when packing resins at process scale. Packing methods can be adapted to obtain simple, highly reproducible packing. Get tips here.

Single-Step Influenza Virus Purification Using an Anion Exchange Resin

A new and simplified anion exchange chromatographic process for the purification of both live and inactivated cell grown H1N1 influenza viruses was established with a recently developed anion exchanger. The resin is designed with an optimized surface extender and pore size for superior accessibility and large biomolecule binding capacity, aiming to overcome common drawbacks of existing ion exchangers for virus purification.

A Mixed-Mode Approach — An Alternative to a Three-Step mAb Purification Process

Monoclonal antibody (mAb) purification methods often involve the use of resin-based chromatography. In this video, we compare a three-step mAb purification workflow, which uses Nuvia Ion Exchange Resins post–Protein A capture, to a two-step purification workflow, which includes a Protein A capture step followed by a mixed-mode chromatography step using Nuvia aPrime 4A Resin, a hydrophobic anion exchange resin. We present an additional two-step purification approach using Protein A resin followed by a calcium affinity cation exchange media, CHT Ceramic Hydroxyapatite XT Media. The results of both studies demonstrate that a high purity product can be attained using one fewer unit operation than traditional workflows.

The Process of Resin Screening

Process development scientists, faced with an increasing number of proteins or complex biomolecules, continuously search for robust purification methods that can be rapidly scaled for manufacturing. What are the optimal purification conditions for high throughput and yield? Which resin or resin combination best purifies the desired protein? How can an efficient, yet cost-effective process be established? The answer: use a systematic screening approach. Read on to learn more.
