This anti-CA9 antibody, S239D/I332E, is a variant version of G250 with amino acid modifications that enhance effector function.
Figure 1 Binding of select anti-CD20Fc variants to human R131FcγRIIa as measured by competition AlphaScreen™ assay.
In the presence of competitor antibody (Fc variant or WT) a characteristic inhibition curve is observed as a decrease in luminescence signal. The binding data were normalized to the maximum and minimum luminescence signal for each particular curve, provided by the baselines at low and high antibody concentrations respectively. The curves represent the fits of the data to a one site competition model using nonlinear regression.

Figure 3 Surface Plasmon Resonance (SPR) (BIAcore) sensorgrams of binding of select anti-EpCAM Fc variants to human R131FcγRIIa.
Figure 4 Plot of the negative log of the KD for binding of select anti-EpCAM Fc variants to human FcγRI, R131FcγRIIa, H131 FcγRIIa, FcγRIIb, and V158 FcγRIIIa.
Figure 5 The absolute affinity differences between the activating receptors and the inhibitory receptor FcγRIb.
The top graph shows the affinity differences between both isoforms of FcγRIIa and FcγRIIb, represented mathematically as [-log(KD)FcγRIIa]-[-log(KD)FcγRIIb]. Black represents logarithmic affinity difference between R131FcγRIIa and FcγRIIb, and gray represents the logarithmic affinity difference between H131 FcγRIIa and FcγRIIb. The bottom graph shows the affinity differences between both isoforms of FcγRIIIa and FcγRIIb, represented mathematically as [-log(KD)FcγRIIIa]-[-log(KD)FcγRIIb]. Black represents logarithmic affinity difference between V158 FcγRIIa and FcγRIIb, and gray represents the logarithmic affinity difference between F158 FcγRIIIa and FcγRIIb.
Figure 6 Plot of the negative log of the KD for binding of 293T-expressed (fucosylated) and Lec13-expressed (defucosylated) anti-EpCAM antibodies to human FcγRI, R131FcγRIIa, H131 FcγRIIa, FcγRIIb, and V158 FcγRIIIa.
*=the data for binding of WT IgG1 defucosylated to FcγRIIb was not determined due to insufficiency of sample.
