Producing defucosylated antibodies with enhanced in vitro antibody‐dependent cellular cytotoxicity via FUT8 knockout CHO‐S cells
23 Feb 2017
Abstract excerpt
To engineer a host cell line that produces defucosylated mAbs with superior antibody‐dependent cellular cytotoxicity, we disrupted α‐1, 6 fucosyltransferase (FUT8) gene in CHO‐S (CHO is Chinese hamster ovary) cells by clustered regularly interspaced short palindromic repeats‐CRISPR associated nuclease 9. The gene knockout cell line was evaluated for growth, stability, and product quality. The growth profile of...
