Creative Biolabs has established a state-of-the-art CAR-T library technology based on T cell display. CAR genes with diverse antibody fragments (e.g. scFv, Fab, VHH, scFab) against a certain target are constructed into vectors to form the CAR-T libraries with capacity around 108. T lymphocytes will display these antibodies on the surface and high-throughput screening approaches can be performed.
