(a) Schematic representation of the domain arrangement of human FcγRI, FcγRIIIA and variants thereof. Green and blue ovals correspond to FcγRI and FcγRIIIA domains, respectively. The low-affinity FcγRIIIA/F158 allotype was used to obtain a larger affinity range when characterizing variants. (b) Binding of human IgG1 at varying concentrations to FcγR variants as measured by ELISA. Standard deviations are indicated by error bars and represent triplicate measurements within the same experiment. |
