AbstractDESCRIPTION (provided by applicant): We propose to develop an inexpensive high-throughput means of selecting and identifying antibodies to both unmodified and modified protein, peptide, and non-peptide antigens. The specific goals of this proposal are to complete a proof-of-concept using aqueous droplets in an oil emulsion for identification and isolation of scFv antibodies. Compartmentalization of recombinant-phage-producing E.coli cells is used to individually query the ability of each scFv to bind to an tigen-coated beads. We propose to develop and test these methods on a phosphopeptide epitope found on the protein Her2. The successful completion of this SBIR and subsequent Phase II goals will have considerable direct impact on the development of new ther apeutic targets, and immunotherapeutic, prognostic, and diagnostic biomarkers. PUBLIC HEALTH RELEVANCE: Gene arrays enabled great breakthroughs in our understanding of the underlying biological processes that occur in cells and tissues. These increased und erstandings have already led to new approaches to diagnosis and treatment of major diseases, including cancer, diabetes and Alzheimer's. We are now entering a post-genomic era where the need for proteomics tools is becoming increasingly important. The tech nical challenges for proteomic tools are far greater than those encountered during the genome project. This proposal describes the high-throughput manufacture of antibodies for measuring protein abundance. The successful completion of this SBIR and our com bined future goals will have significant direct impact on the development of new therapeutic targets as well as immunotherapeutic, prognostic, and diagnostic biomarkers.
