摘要
The present disclosure provides a method of controlling the Antibody Dependent Cellular Cytotoxicity (ADCC) activity of a glycosylated and afucosylated IgG1 antibody composition. In exemplary embodiments, the method includes (1) determining the ADCC activity of a glycosylated and afucosylated IgG1 antibody composition; and (2) increasing or decreasing the ADCC activity of the IgG1 antibody composition by increasing or decreasing the amount of terminal β-galactose in the afucosylated glycan species at the consensus glycosylation site. Related methods of matching ADCC activity of a reference glycosylated and afucosylated IgG1 antibody composition and methods of engineering a specific target ADCC activity of a glycosylated and afucosylated IgG1 antibody composition are further provided herein.
