Based on the phage and other organisms display technology, established a series of antibody drug discovery and optimization platform, including the whole human antibody library, alpaca single domain antibody library, mouse immune library type, integrated our phage display technology and deep understanding of antibody genome and physical and chemical characteristics, with large capacity, good diversity, antibody, physical and chemical properties superior characteristics, will greatly help our bispecific antibody and multiple specific antibodies, antibody editing construction and research and development. The antibody display technology platform will also play a huge role in the affinity modification, ADC-antibody discovery, humanization, and stability improvement.
