7:15 am Conference Registration
7:30 Breakfast Presentation: Leveraging Gene Synthesis for the Systematic Optimization of Protein Production
Mark Welch, Ph.D., Director, Gene Design, DNA2.0, Inc.
Current gene design and synthesis technologies allow control over sequence features critical for protein production. Variables at the levels of ORF coding, vector elements, protein sequence and the host genome can be essential for maximum system yield. We describe the application of gene synthesis and informatics technologies for the systematic study and optimization of such variables, with an emphasis on gene coding variables that influence protein yield in a number of commonly employed production hosts.
8:30 Chairperson’s Remarks
James E. Galen, Ph.D., Professor, Medicine, Chief, Salmonella Live Vector Vaccine Section, University of Maryland School of Medicine
8:35 Molecular Cloning, Overexpression and an Efficient One-Step Purification of αVβ5 and α5β1 Integrin
Lawrence J. Tartaglia, Ph.D., Research Scientist, Biochemistry and Molecular Biology, Center for Structural Biology, University of Florida
Recombinant αVβ5 and α5β1 integrin expression systems were created for the large-scale production of integrin extracellular domains that take advantage of Fos and Jun dimerization for expression in HEK293 cells and SF9 insect cells. Both integrin heterodimers were purified in a one-step nickel column purification scheme, characterized and yields were in quantities suitable for multiple applications including structural biology and functional assays.
9:05 Brevibacillus, a New Tool for High-Level Intracellular Expression of Bacterial Antigens
Domenico Maione, Ph.D., Unit Head, Cloning and Expression, Novartis Vaccines and Diagnostics
Brevibacillus choshinensis, a novel Gram positive Expression System, is an easy-to-handle non-sporulating bacterium. One major drawback that limits applicability is the absence of expression vectors based on inducible promoters. We achieved high level of intracellular protein expression in Brevibacillus, using the pHis1522 vector carrying the B. megaterium xylose-inducible promoter (PxylA). Our results suggest that the intracellular protein expression in Brevibacillus could be an attractive strategy to produce proteins that are poorly expressed, toxic or degraded in E. coli.

10:50 A New and Versatile Concept for Systematic Multi-Gene Constructs Generation
Wassim Abdulrahman, Ph.D., Research Scientist, Mechanisms of Cancer, Friedrich Miescher Institute for Biomedical Research and CPC Novartis
Protein complexes expression is a major challenge for drug discovery. Although several molecular biology methods are well established for generating multi-gene constructs, none of these methods are adapted to in-parallel screening strategies. I will describe a novel and versatile method specifically designed for robotized screening of multi-protein expression.
11:20 Data Management and Automation of Protein Production Workflows in Biologics R&D
Christoph Freiberg, Ph.D., Senior Scientist, Biologics Research, Bayer HealthCare
Our comprehensive workflow platform supports highly parallelized antibody and tool protein production. It uniquely integrates in silico cloning, construct annotation and molecule registration functionalities, while supporting automated and high-throughput evaluation of expression systems of different scales. The molecule’s historical record is faithfully recorded, from early discovery campaigns to engineering and late-stage development. A single system stores molecule hierarchies and associated key expression, purification and analytics data. We thus glean essential information for improving product quality and optimizing production processes.
