Mixed-Mode Chromatography Resins​ for Biomolecule Purification

This webcast features: Dr. Xuemei He, R&D Chromatography Media Chemistry Manager, Bio-Rad Laboratories Mixed-mode chromatography has emerged as a viable purification method for biomolecules that are otherwise difficult to purify using traditional chromatography platforms and other established means. Scientists are gaining an increased understanding of mixed-mode mechanisms and how these interactions impact selectivity. The industry is becoming more adept at including mixed-mode steps in production processes while also working to address robustness, platform fit, and productivity. This webinar will examine…

Effectively Securing Cell and Gene Therapies with Closed Systems

With their innovative new treatments, cell and gene therapies (CGT) are growing rapidly. But their traditional production processes don’t allow the supply of these therapies to keep up with demand. Historically, these therapies are produced for small patient populations in clinical trials using laboratory scale equipment and utilizing manual, open processes completed under laminar hoods. But manufacturers looking for more efficiency and flexibility are turning to new solutions. One key area of interest is the implementation of a closed system…

Characterization Platform for Structural and Functional Feature Investigation of Bispecific Molecules

Bispecific antibodies (BsAbs ) bind to two or more targets which could be different antigens or different epitopes. Structurally, one type of bispecific antibody is similar to an IgG which contains an Fc region, and other bispecifics do not have an Fc region and typically have a relatively small molecular weight. Therefore, the characterization for a bispecific is more challenging than for a typical monoclonal antibody because of this variation in structure. The poster here discusses a set of platform…

Understanding and Controlling Raw Materials Variation in Cell Culture Media

The FDA requires biopharmaceutical manufacturers to understand and control sources of variation according to the risks they present to process and product. Cell culture media and feeds have been shown to affect cellular performance, product quality, or both. The evolution of media formulas to those that are serum-free and chemically defined poses both a challenge and an opportunity. The challenge is identifying which of the many components have the greatest impact on cells and the molecules they produce. The opportunity…

Cryogenic Temperatures and Cell Viability

This webcast features: Dr. Peter Kilbride and Dr. Julie Meneghel, Senior Research Scientist and Cryobiologist, GE Healthcare Life Science In this webinar, we will address fundamentals of cryobiology to (1) understand why a cryopreservation protocol is needed, (2) see what happens biologically to cells while cooling, and (3) allow attendees to design an optimized protocol for their cell type and cryopreservation configuration (e.g., sample size). We will cover the importance of applying controlled-rate cooling and how to best tune it to…

Ask the Expert: Accelerating Development and Manufacturing Platforms for Viral Vectors

Bai-wei Gu, Juan Lagos, and Matthew Weaver (heads of cell line development, upstream process development, and downstream process development groups, respectively, at WuXi Advanced Therapies, ATU) joined forces on 29 October 2019 to feature their company’s viral-vector manufacturing capabilities for cell and gene therapies. In addition to adherent platforms for lentivirus (LV) and adenoassociated virus (AAV) vectors, ATU soon will offer suspension-cultured viral vector platforms for them as well as analytical measures that support release testing. Transitioning from adherent to…

Ask the Expert: Best Practices for Aseptic Sampling from Stainless-Steel Equipment

Turn-key single-use aseptic sampling devices (ASDs) have diminished bioprocess contamination risks significantly. But depending on testing, facility, and storage needs, some ASD container types are more effective than others are. Bobbi Allen (technology expert at Sartorius Stedim Biotech North America, SSB) focused her 8 January 2020 “Ask the Expert” presentation on “what, why, when, and where” operators must sample aseptically from stainless-steel tanks. Using data from in-house testing of aseptic sampling containers, Allen offered key considerations for sterility, process monitoring,…

Introducing New Digital Tools to Enhance Raw Material Verification

This webcast features: Antonia Guerra, Global Digital and Data Science Leader, Field & Safety Instruments, Thermo Fisher Scientific™ This webinar presents the new virtual companion to the Thermo Scientific™ TruScan™ RM Handheld Raman Analyzer, the Virtual TruScan™ RM (VTR) App, which creates efficiencies in material identity verification. This first-of-its-kind digital tool puts the TruScan RM’s decision algorithm in the cloud and allows for method validation and spectral re-processing without the need for a physical sample. With the VTR app, wait…

Ask the Expert: Highly Sensitive Host-Cell Protein Analyses Using Novel Chromatography Technology

Geert Van Raemdonck (global field support expert at PharmaFluidics) and Koen Sandra (scientific director of the Research Institution for Chromatography, RIC) teamed up for a 10 October 2019 “Ask the Expert” webinar to introduce micro Pillar Array Column (μPAC™) technology for liquid chromatography–mass spectrometry (LC–MS) for host-cell protein (HCP) detection. Van Raemdonck explained that μPAC technology approaches chromatography differently than does packed-bed technology. Microfluidic channels with arrays of free-standing pillars are etched lithographically into a silicon wafer. The resulting permeability…
