Figure 3. Competition between different VHH for binding toward recombinant envelope proteins.

Competition matrix of VHH to gp140_UG37 (A) and gp140_CN54 (B). The values shown represent the mean binding of envelope protein in presence of the competitor VHH. The effect of competition is expressed in percent of positivity and marked mutual cross-competition (<30%) are shown by light grey cells and weak mutual cross-competition (>75%) by dark grey cells.
