OmniAb licenses cutting-edge discovery research technology to pharmaceutical and biotech companies and academic institutions to enable the discovery of next-generation therapeutics. Our technology platform creates and screens diverse antibody repertoires and is designed to quickly identify optimal antibodies and other target-binding proteins for our partners’ drug development efforts. At the heart of the OmniAb platform is what we call Biological Intelligence™, which powers the immune systems of our proprietary, engineered transgenic animals to create optimized antibody candidates for human therapeutics. We believe the OmniAb animals comprise the most diverse host systems available in the industry. These technologies paired with xPloration, our AI-powered high-throughput single B-cell screening platform, are used to identify fully-human antibodies with exceptional performance and developability characteristics. We provide our partners both integrated end-to-end capabilities and highly customizable offerings, which address critical industry challenges and provide optimized discovery solutions.
