Extended Data Fig. 8: Mouse and human C1q binding of Fc domain variants of IgG1.
The capacity of IgG1 Fc domain variants to interact with mouse (a) and human (b) C1q was assessed by ELISA (n= 1 experiment performed in duplicates). The KA (K322A) variant, which has previously described as a complement-deficient mutant28, was included as control.
