    • The implementation of high- throughput ( HTP) cloning and expression screening in Escherichia coli by 14 laboratories in the Structural Proteomics In Europe ( SPINE) consortium is described. Cloning efficiencies of greater than 80% have been achieved for the three non- ligation- based cloning techniques used, namely Gateway, ligation- indendent cloning of PCR products ( LIC- PCR) and In- Fusion, with LIC- PCR emerging as the most cost- effective. On average, two constructs have been made for each of the approximately 1700 protein targets selected by SPINE for protein production. Overall, HTP expression screening in E. coli has yielded 32% soluble constructs, with at least one for 70% of the targets. In addition to the implementation of HTP cloning and expression screening, the development of two novel technologies is described, namely library- based screening for soluble constructs and parallel small- scale high- density fermentation.

  • Eukaryotic expression: developments for structural proteomics.
  • 2006
  • Ingår i: Acta Crystallographica Section D: Biological Crystallography. - 1399-0047 .- 0907-4449. ; 62, s. 1114-1124

    • The production of sufficient quantities of protein is an essential prelude to a structure determination, but for many viral and human proteins this cannot be achieved using prokaryotic expression systems. Groups in the Structural Proteomics In Europe (SPINE) consortium have developed and implemented high-throughput (HTP) methodologies for cloning, expression screening and protein production in eukaryotic systems. Studies focused on three systems: yeast (Pichia pastoris and Saccharomyces cerevisiae), baculovirus-infected insect cells and transient expression in mammalian cells. Suitable vectors for HTP cloning are described and results from their use in expression screening and protein-production pipelines are reported. Strategies for co-expression, selenomethionine labelling (in all three eukaryotic systems) and control of glycosylation (for secreted proteins in mammalian cells) are assessed.
