Figure 6.
Competition of 17A7, 17B10 and 3A6 mAbs with human COVID-19 convalescent sera or mRNA post-vaccination sera for binding to immobilized original RBD. (A) Schematic illustration of competition between mouse mAbs and human COVID-19 specific polyclonal sera. The % of residual (B) 17A7, (C) 17B10 or (D) 3A6 after competing with human COVID-19 convalescent sera or post-vaccination sera as compared to the wells that contained only mAbs were plotted by nonlinear regression. Data are expressed as mean ± s.e.m (n = 6–8 sera/group).
