Figure 7. (A) Mean EC₅₀ value and(B) Mean Relative ADCC activity of select AbX AF-blend samples with effector cells carrying different FcγRIIIa genotypes (VV: homozygous V158; VF: heterozygous with both V158 and F158; FF: homozygous F158). Relative ADCC activity was calculated by inverse normalization of EC₅₀ values of samples with EC₅₀ value of the sample containing 0% afucosylated material. Data presented are mean values from at least five in vitro ADCC experiments using different donors; error bars indicate corresponding standard deviations.
