Protein Purification and Recovery

Streamlining & Innovating Processes

January 21-22, 2020

Part of the Process Technologies & Purification pipeline

Protein-based biologics depend on the expression and purification of viable proteins that can be scaled up and transported for human use. But, purifying protein remains a constant bottleneck that often involves time-consuming steps and techniques. However, today breakthrough technologies and tools are being employed to improve processes leading to properly folded proteins. CHI’s Protein Purification and Recovery conference examines the strategies that efficiently lead to pure protein. This leading conference illustrates how ‘traditional’ strategies (protein A, chromatography, affinity tags) are being innovated and enhanced, while also demonstrating new tools that are being introduced and integrated to help streamline purification while ensuring quality. This conference will also explore the finesse required when purifying complex molecules, such as membrane proteins, in the ever-present quest for purity.

KEYNOTE PRESENTATION

2:05 Continuous Purification of Antibody with Precipitation, a Process with Non-Interrupted Mass Flow of the Product

Alois Jungbauer, PhD, Professor and Head, Institute of Bioprocess Science and Engineering, Biotechnology, University of Natural Resources and Life Sciences (BOKU)

We developed a new continuous precipitation process where the mass flow of the product is not interrupted. This process is robust, because fluctuations in the feed stream can be readily handled and can be easily realized as a disposable unit, because the necessary equipment, such as tubing, fittings, static mixers, and hollow fiber modules, are commercially available and do not require surge tanks. This process is truly continuous compared to other, quasi/semi-continuous chromatography processes, which require cyclic operation.

2:45 Rapid Protein Production and Purification by Continuous Flow

Weiss_GregoryGregory Weiss, PhD, Professor, Chemistry, Pharmaceutical Sciences, Molecular Biology & Biochemistry, University of California, Irvine

The vortex fluid device invented by collaborator Professor Colin Raston (Flinders University, Australia) and the speaker, Professor Weiss, accelerates protein folding and purification using micrometer-scale thin fluidics to input mechanical energy, micromixing, and centrifugal force. The approach allows 10-minute purification from cell lysate to single band on SDS-PAGE and avoids centrifugation. Applying thin chromatographic layers avoids the clogging inherent to conventional chromatography and simplifies the protein purification process.

Wood_DavidDavid Wood, PhD, Professor, Chemical and Biomolecular Engineering, Microbiology, Chemistry & Biochemistry, Ohio State University

We have developed a functional prototype capture resin based on a self-cleaving intein tag and used the system to successfully purify several affinity-tagged target proteins. The proteins were expressed in E. coli or mammalian cells and purified using a single-column format, where the tag is automatically removed during the purification process. We will present data on the resulting purity and yield for several protein targets, including established therapeutic glycoproteins.

YANG-Yan-pingYan-ping Yang, PhD, Associate Vice President and Head, Bioprocess R&D, North America, Sanofi Pasteur

Over the last three decades, there has been significant evolution in downstream purification technologies to support vaccine development. The advances in this field have greatly benefited the vaccine industry to achieve consistent product purity and quality in a timely and cost-effective manner. In recent years, the vaccine field has attracted significant interest due to a rapid growth of the global market. However, it remains a challenging and complex industry. This presentation reviews the constraints and complexities in vaccine purification development and manufacture and describes the evolution of purification technology innovation to overcome these challenges, with an outlook into the future.

PURIFYING ANTIBODIES

10:35 Understanding and Exploiting the Nuances of Ion-Exchange Purification of mAbs

Lenhoff_AbrahamAbraham M. Lenhoff, PhD, Allan P. Colburn Professor, Chemical and Biomolecular Engineering, University of Delaware

Although the general principles of ion-exchange purification of proteins are well-known, observed column behavior can be appreciably influenced by effects at the particle and the column level that have received less attention. This presentation will discuss such effects as seen in both modeling studies and experimental observations; and will point out how such behavior can be exploited to improve separations performance.

11:05 Design and Application of Fc-Containing Bispecific Antibody Platform for Immunotherapy

Rashid_RumanaRumana Rashid, PhD, Lead Scientist, Protein Sciences, Xencor, Inc.

Xencor’s heterodimeric Fc domain is a robust platform that enables us to develop bispecific antibodies and Fc fusion proteins efficiently. Its straightforward purification of the heterodimeric species is achieved through engineering isoelectric point differences in the Fc region, followed by a novel set of Fc substitutions. This can successfully produce heterodimer yields over 95% with little change in thermostability. We have exploited this platform to develop anti-cancer drugs of different classes. Finally, we present manufacturing data reinforcing the robustness of the heterodimeric Fc platform at GMP scale.

11:35 Using a Design of Experiment (DoE) Approach to Develop a Cost-Effective Antibody Fragment Purification Process

Lai_Wan-ChingWan-Ching Lai, PhD, Principal Scientist, Diagnostics, Abbott Laboratories

With the constant improvements to genetic engineering the production of recombinant Fabs has become a viable alternative to antibodies. Here, we demonstrate the development of robust, cost-effective CH1-XL affinity chromatography process using a Design of Experiment approach.  Further improvements include the implementation of a cycling purification approach to increase overall yield without increasing the amount of resin required.  The optimized process resulted in near 15-fold increase in yield per ml/resin.

4:05 Production of Complex Target Proteins to Enable Antibody Generation

Smith_CoreyCorey Smith, PhD, Senior Scientist, Abbvie Bioresearch Center

Obtaining stable recombinant proteins that resemble the native target structure and function is essential for the advancement of pipeline projects. The complexity of many targets like membrane proteins poses a challenge, and I will present methods that we have developed to purify and stabilize such complex proteins. Case studies will be presented for the preparation of co-receptor complexes and of multi-span transmembrane proteins that enabled the generation of agonist and IHC antibodies, respectively.

4:35 Tools to Evaluate Protein A Chromatographic Stationary Phases

Pabst_TimothyTimothy M. Pabst, PhD, Principal Scientist, Protein Purification & Downstream Process Development, AstraZeneca

As therapeutic use of monoclonal antibodies and related molecules continues to grow, Protein A chromatography remains the primary mode of purification due to high specificity, platformability, and strong regulatory track record. But as the biopharmaceutical industry faces pressures for lower costs, process developers continue to look for opportunities to improve productivity and lower cost of goods. In this presentation, we provide the tools that can be used to evaluate Protein A stationary phases, many of which offer high binding capacities coupled with excellent impurity clearance.

5:05 Enhancing Virus Filter Throughput for Hydrophobic Proteins Using a High-Throughput Screening Tool

Wang_LuLu Wang, PhD, Associate Director, CMC Process Development, Teva Pharmaceuticals USA, Inc.

Virus reduction filtration (VRF) is considered as one of the most robust and effective virus clearance steps used in the manufacture of biologics. However, for hydrophobic proteins, VRF process development can be challenging due to filter fouling, which results in low throughput. This presentation is a case study that compares the VRF performance based on protein hydrophobicity and demonstrates a strategy to improve the viral filter throughput to enable GMP manufacturing facility fit.

5:35 Will the Real KRAS Please Stand Up?

Messing_SimonSimon Messing, PhD, Scientist II, Protein Expression Laboratory, Leidos Biomedical/Frederick National Laboratory for Cancer Research

Human KRAS GTPase is one major hub involved in processing growth-related cellular signals. Hence, mutations in KRAS drive or contribute to roughly 30% of all cancers and make for a desirable target for therapeutic intervention. A large part of this work is done on recombinant KRAS with a non-native N-terminus. Here we have produced KRAS with proper post-translational modifications on both N- and C-termini from mammalian and insect expression systems.
