摘要: The new era of functional genomics demands several antibodies as specific detection reagents for proteins, their complexes and post-translational modifications. Only in vitro antibody selection technologies are able to provide the required throughput generate these large numbers. Phage display is most widely used technology antibodies. major bottleneck a phage pipeline production monoclonal fragments screening further analysis. In this study, we describe development improved protocols single chain Fv (scFv) 96-well microtitre plates (MTPs) Escherichia coli. Four scFvs were expressed using expression vector pOPE101-XP analyse influence set different parameters on production. Further, six pHAL14 investigate effect those that from pOPE101-XP. Yield MTPs was influenced by variety conditions also strongly dependent individual scFv clone. Although it not possible deduce optimal applicable all tested scFvs, combined protocol developed which over standard methods.
