Apparent KD values of group 1 and group 3 supernatants with the BG505.DS.SOSIP.S613A trimer. Group 1 includes supernatants with BG505.N611Q neutralization IC50 values below 1 μg/mL. Group 3 includes non-neutralizing supernatants or supernatants with IC50 values above 1 μg/mL. A red bar and error bars indicate median and interquartile range. A blue dashed line indicates the highest KD value (2.58 × 10−8M) in group 1. The blue number indicates that 94% of group 3 supernatants are above the blue line.
