Title
High-throughgput phage-display screening in array format
Abstract

•Phage-display and selection tools offer a powerful way for antibody identification.•Phage antibody microarrays avoid such time-consuming and costly steps.•Phage-display arrays allow high-throughput analysis of protein expression profiles.•Displaying phage libraries on protein chips offers an alternative analysis method.•Proteomics approaches improve protein identification and validation.

Emerging technologies for the design and generation of human antibodies require improved approaches enabling their screening, characterization and validation. Currently, strategies based on ELISA or western blot are used to that aim. However, the ever increasing number of novel antibodies generated would benefit from the development of new high-throughput (HT) platforms facilitating rapid antibody identification and characterization. Herein, we describe a protein chip bearing recombinant phage particles and based on a large phage antibody library. In this paper we have set forth a novel implementation which provides a powerful and simple methodology enabling the identification of single-chain variable fragments (scFv). As a proof-of-principle of this method, we tested it with recombinant antigen (human recombinant interleukin 8). Additionally, we developed a novel bioinformatics tool that serves to compare this novel strategy with traditional methods. The method described here, together with associated informatics tools, is robust, relatively fast and represents a step-forward in protocols including phage library screenings.
