Improving and Intensifying Vaccine Purification By Implementing Affinity Chromatography

This webcast features: Zoltan Gulyas, Field Applications Specialist, Thermo Fisher Scientific Vaccines are well-established tools in the fight to eradicate infectious diseases. Over the past few decades, vaccine production has advanced significantly, largely by the introduction of new molecule modalities. However, these new types of vaccine candidates often require multiple chromatographic steps to obtain the desired level of purity. Developing an efficient purification process using the classical surface chemistries such as ion exchange and hydrophobic interaction requires significant amounts of…

How to Halve the Costs of Antibody Purification?

This webcast features: Romain Dabre, Senior Product Manager, Tosoh Bioscience Downstream processing is responsible for up to 80% of the entire production costs of biotherapeutics. Given the current drive to reduce manufacturing costs for biological therapeutics, streamlining downstream processing is necessary for chromatographers and process engineers. In this presentation, we showcase the benefits of using only two chromatography processes to purify monoclonal antibodies compared to the standard industrial process. Combining high-performance Protein A capturing and a single polishing step on salt-tolerant…

Best Practices for Ensuring High Virus Clearance When Using Anion Exchange Membrane Adsorbers

This webcast features: Sherri Dolan, Global Technology Consultant, Separations Marketing Group, Sartorius Stedim Biotech The risk of viral contamination is a concern for all biopharmaceuticals and vaccines derived from cell lines and can have serious implications. Contamination events can cost millions of dollars in investigation, clean-up, corrective action, and manufacturing plant downtime. Most importantly, such events pose a safety risk to the patient. To ensure the safety of biological products, regulatory agencies require manufacturing processes to have a validated current…

Advantage of Antibody-Based Selectivity in the Purification of Next-Generation Biologics

The webcast features: Laurens Sierkstra, Senior Director, Business Leader Purification, Thermo Fisher Scientific Advances in biotherapeutics are generating an increasing range of complex molecules that present unique and often complex purification challenges. Affinity chromatography can serve as a platform solution for the purification of these challenging molecule modalities. An effective affinity resin can help to simplify biomolecule purification, reduce the number of purification steps, and reduce the overall cost of goods in biotherapeutic manufacturing. By taking advantage of antibody-based selectivity, camelid…

Webcast: Enabling Digital Chromatogram Review for a Faster and More Reliable Operation

This webcast features: Martin D. Jensen, Senior Engineer, FUJIFILM Diosynth Biotechnologies Chromatogram review is a monitoring method used to verify process performance in packed-bed chromatography processes. By observing key process parameters such as chromatography column outlet conductivity or UV absorbance, it is possible to identify the signs of a poorly packed column, resin degradation, or equipment malfunction. The industry standard practice relies on performing a paper-based qualitative visual comparison of chromatography profiles against a reference batch. This approach leads to a…

Predicting Viral Clearance Using a Non-Infectious MVM Surrogate in Downstream Development

This webcast features: David Cetlin, Senior Director, R&D, Cygnus Technologies As viruses can arise during the manufacture of biopharmaceuticals, regulatory agencies require viral clearance validation studies for each biopharmaceutical prior to approval. These studies are typically conducted in biosafety level (BSL)-2 facilities and require large capital and human resources. Due to these hurdles, process knowledge pertaining to viral clearance is limited during development and characterization. The use of an accurate, economical, and quantifiable non-infectious viral surrogate would enable downstream purification…

To Compress or Not to Compress: What You Need to Know About Packing Resins at Process Scale

This webcast features: Dr. Mark A. Snyder, Manager, Process Chromatography, R&D Applications Group, Bio-Rad Laboratories Join our expert, Dr. Mark A. Snyder, to learn best practices and guidelines for successfully packing different types of chromatography resins. This includes incompressible resins like CHT Ceramic Hydroxyapatite Media as well as traditional compressible resins. CHT is an easy-to-use mixed-mode media and has high specific gravity, a rapid settling rate, and sensitivity to mechanical shear. These variations from traditional compressible resins have to be…

Accelerating mRNA-Based Therapy Development with Scalable Purification of In Vitro Transcribed mRNA

This webcast features: Kelly Flook, Senior Product Manager, Purification Products, Thermo Fisher Scientific The diversity of potential mRNA-based therapies has led to increased interest in using synthetic mRNA as a tool in the treatment of multiple diseases, such as cancer, stem cell therapies, and infectious diseases. Nevertheless, obtaining larger quantities of synthetic mRNA for clinical treatment remains a challenge. Currently available mRNA purification methods are becoming a bottleneck for large-scale manufacture as the limits of research-scale purification techniques are realized.…
