Methods and compositions for discovering target-specific antibodies using antibody repertoire arrays (ARA)

摘要

The invention provides antibody arrays specific for target antigens. Methods for discovery and compositions comprising native human antibodies, arrays comprising such antibodies, immortalized B cells expressing such antibodies and non-immortalized B cell libraries comprising B cells expressing such antibodies are provided. The invention provides a method for screening monoclonal antibodies for functional effects on cell surface molecules such as receptors using antibody repertoire arrays specific for target cell surface molecules. Functional antibodies directed to a target and therapeutics derived from such antibodies are also provided. High throughput and parallel screening for potentially therapeutic antibodies are provided. Antibodies directed to functional epitope clusters corresponding to a target and vaccines and therapeutics derived from such antibodies are also provided.
