High-Throughput Protein Expression

Strategies for Successful Outcomes

May 2-3, 2013

The steps required to prepare an expression system prior to scale-up have been plagued with difficulties through the past decades. Methods for testing the system parameters, including temperature, HT selection and fine-tuning of hosts, clones, culture media and containers are constantly being introduced, and then go by the wayside as they fail to meet expectations. Novel methods and strategies are crucial to successfully prepare the elements needed. This conference will provide the latest strategies and techniques to make this stage of the protein expression process more effective and efficient.

» 1:40 KEYNOTE: 

Novel Technologies to Enable High-Throughput Expression

Govind RaoGovind Rao, Ph.D., Professor and Director, Center for Advanced Sensor Technology, University of Maryland

Everybody wants high throughput, but what is the best approach to produce proteins of consistent quality? We will explore technologies that enable small scale process monitoring and control to arrive at the desired outcome. In addition, we will present strategies that leverage advances in micro-scale bioprocessing to make proteins on demand.


2:10 Filtering "Genic" Open Reading Frames from Genomic DNA by Antibiotic Selection

Sarah D'AngeloSarah D'Angelo, Ph.D., Researcher, Los Alamos National Laboratory

The availability of ORF libraries obtained with β-lactamase-based filtering method, combined with phage display and protein-protein interaction studies,or with protein structure determination projects, can lead to identification and structural determination of functional genic ORFs. ORF libraries represent a useful tool to proceed towards high-throughput functional annotatation of newly sequenced genomes.
