An anti-human interleukin 5 receptor (hIL-5R) humanized immunoglobulin G1 (IgG1) and an anti-CD20 chimeric IgG1 produced by rat hybridoma YB2/0 cell lines showed more than 50-fold higher(More)
To generate industrially applicable new host cell lines for antibody production with optimizing antibody-dependent cellular cytotoxicity (ADCC) we disrupted both FUT8 alleles in a Chinese hamster(More)
PURPOSE Recent studies have revealed that fucosylated therapeutic IgG1s need high concentrations to compensate for FcgammaRIIIa-competitive inhibition of antibody-dependent cellular cytotoxicity(More)
