- 纯化技术 -
As more and more biological drugs are developed, an increasing demand falls on achieving pure protein, either for research or for therapeutic development. Achieving pure protein quicker and cheaper is essential, while also ensuring protein quality. Researchers must streamline the steps required to achieve purity, but protein’s intrinsic nature can cause headaches and frustrations. When faced with greater protein challenges, such as membrane proteins, expanding the purification toolbox becomes extremely helpful.

In addition, new technologies are continually emerging that offer support, and traditional techniques, such as chromatography and Protein A, are also being innovated. The “Protein Purification Technologies” conference explores current strategies that are proving successful, and looks at new ways to streamline techniques in the continual quest for purity.

Massimo Morbidelli, Professor, Chimica, Materiali e Ingegneria Chimica, Giulio Natta, Politecnico di MilanoMassimo Morbidelli, PhD, Professor, Chimica, Materiali e Ingegneria Chimica, Giulio Natta, Politecnico di Milano

Continuous countercurrent chromatography is recognized as the technology of choice for a number of instances in the area of protein purification. Approaching its maturity stage, this technology has to be reconsidered with respect to crucial aspects for its future development. In particular, we discuss issues related to scalability in the GMP environment, model-based process characterization and validation, as well as process automation, control and digitalization particularly in the context of continuous integrated manufacturing.

14:35 Tailor-Made Solvent Systems for Continuous Aqueous Two-Phase Extraction of Biomolecules

Brandenbusch_ChristophChristoph Brandenbusch, PhD, Group Leader, Biochemical and Chemical Engineering, Technische Universität Dortmund (TU Dortmund)

Extractions based on aqueous two-phase system (ATPS) were shown to have an enormous potential for the extraction of biomolecules. It is essential to identify a suitable tailor-made ATPS using profound knowledge on the molecular interactions in solution to influence the partitioning of the biomolecule and allow for the highest possible yield. We will present a novel method for this purpose as well as a new technology for a continuous ATPE.

16:00 A Microfluidic Platform for Antibody Manufacturing Optimization

Aires_Barros_RaquelRaquel Aires Barros, PhD, Full Professor, Bioengineering, IBB – Institute for Bioengineering and Biosciences, Instituto Superior, Universidade de Lisboa

The number of biotechnology-based pharmaceuticals in the late-stage pipeline has been increasing more than ever in particular monoclonal antibodies (mAbs) representing a quarter of all biopharmaceuticals in clinical trials. As a result, there is an enhanced demand for more efficient and cost-effective processes for antibody manufacturing. Here, the potential of miniaturization as a high-throughput screening tool to speed up process development of antibodies is explored.

MEMBRANE PROTEIN PURIFICATION

08:30 Chairperson’s Remarks

Christoph Brandenbusch, PhD, Group Leader, Biochemical and Chemical Engineering, Technische Universität Dortmund (TU Dortmund)

08:35 The Gram-Negative Bacterial Cell Surface: How to Study Its Protein Components and How to Remove Endotoxin

Linke_DirkDirk Linke, PhD, Professor, Molecular Microbiology, Biosciences, University of Oslo

In our recent work, we have developed methods to express bacterial outer membrane proteins in ways that allow direct NMR studies in the native environment. As experts in membrane protein purification, we constantly develop expression strains and methods for quality control. In that regard, we recently found a small protein with high affinity for bacterial endotoxin, that we hope can be used for endotoxin detection and removal.

09:05 Sane in the Membrane – Salipro One-Step Reconstitution of Membrane Proteins

Frauenfeld_JensJens Frauenfeld, PhD, CEO, Salipro Biotech AB

Membrane proteins are important drug targets (GPCRs, ion channels), yet are notoriously difficult to work with. We have developed a novel one-step approach for the incorporation of membrane proteins directly from crude cell membranes into lipid Salipro particles. This direct approach presents new opportunities for the analysis of novel drug targets. Furthermore, we present how the Salipro system can be used to generate antibodies against important membrane proteins.

09:35 A Tricky Endeavour: Production of Membrane-Bound P450s

Spadiut_OliverOliver Spadiut, PhD, Associate Professor, Chemical, Environmental and Bioscience Engineering, Integrated Bioprocess Development, Vienna University of Technology (TU Wien)

Cytochrome P450s (P450s) comprise one of the largest known protein families. They occur in every kingdom of life and catalyze essential reactions, such as carbon source assimilation, synthesis of hormones and secondary metabolites, or degradation of xenobiotics. Due to their outstanding ability of specifically hydroxylating complex hydrocarbons, there is a great demand to use these enzymes for biocatalysis. However, this requires a great understanding of these enzymes – thus we need to know their protein crystal structure. In this talk I will present how we recombinantly produced and purified a plant cytochrome P450.

10:05 Networking Coffee Break

PURIFYING BISPECIFIC ANTIBODIES

10:35 Overcoming Some Challenges in the Purification of Bispecific Antibodies

Correia_AnaAna Correia, PhD, Scientist, Biologics Optimization, Amgen, Inc.

Bispecific antibodies are an emerging class of therapeutics which are engineered to simultaneously bind two distinct targets. Production and purification of these molecules is challenging due to the presence of byproducts such as aggregates and half-antibodies, which are difficult to eliminate by conventional chromatographic techniques. Here I show results from a novel Protein A chromatography strategy that removes these impurities, thereby reducing processing cycle-time and improving product quality.

11:05 Novel Protein A Small and Large-Scale Purification Platforms for Bispecific Antibodies

Mahmoudi_AfshinAfshin Mahmoudi, MS, Scientist II, Biotherapeutics, Celgene Corp.

Our goal was to develop a robust 1-2 step process that can be applied for the purification of most bispecific antibodies (BsAbs). In this study, we present a BsAb purification process consisting of affinity capture using a novel Protein A chromatography resin, and subsequent screening of chromatography resins (ion exchangers, HIC or multimodal resins) for additional polishing. Recovery and purity indicate a robust purification platform for BsAb programs. This novel platform simplifies process development, reduces time and expense, and ultimately time to market.

13:35 Advanced Chromatography-Free Protein Purification Strategies Enabling High-Resolution Structure Determination of Large, Labile Multi-Subunit Biological Assemblies and Drug Discovery

Chari_AshwinAshwin Chari, PhD, Project Group Leader, Structural Dynamics, Max Planck Institute for Biophysical Chemistry

Biochemical purification of large, labile assemblies remains a formidable challenge and often fails when strategies suitable for single biomolecules are adapted to larger complexes. Here, I will present the development of chromatography-free purification strategies, which enable the purification of large biological assemblies in high-yield and high-quality. The strategies reported here have enabled the structure determination of proteasomes and fatty acid synthases at unprecedented resolution and opened up new venues for drug discovery.

14:05 Improved Downstream Processing of Recombinant Proteins Using Aqueous Two-Phase Systems Composed of Ionic Liquids

Pedro_AugustoAugusto Pedro, PhD, Postdoctoral Fellow, Chemistry, CICECO – Aveiro Institute of Materials, University of Aveiro

Previous studies have shown that ionic liquids display highly interesting features concerning protein stabilization, and by properly tailoring their anion/cation pairs, increased selectivity towards the target protein can be achieved in IL-ATPS. Process intensification and scale-up of IL-ATPS for the purification of recombinant proteins can be achieved by centrifugal partition chromatography (CPC), in which the stationary phase is also liquid and kept by centrifugal force.

14:35 Purification of Viruses and Virus-Like Particles for Structural Studies

Stehle_ThiloThilo Stehle, PhD, Professor, Interfaculty Institute of Biochemistry, University of Tübingen

Structure-function studies of viruses require large amounts of intact particles of either complete, infectious virus or infection-deficient virus-like particles. I will report on strategies that we use in my group to express and purify such particles, and I will present data on the structural analysis of these particles.
