The advantages of synthetic antibody technology have gained increasing attention. A well-designed synthetic antibody library is more efficient than conventional phage displayed libraries, and the derived antibodies likely have better developability. Not only can it bypass the need for humanization and the limitations of animal immune systems, but it is also better suited for engineering and screening method development. BioDuro-Sundia builds antibody libraries in Fab and VHH formats to meet the diverse requirements of drug discovery. We are expanding our libraries into different designs and formats to cover more epitopes and applications.
