Figure 2. Angle of approach to the Env trimer by PGT121 family members as determined by EM.
Schematic representation of Abs from the PGT121 phylogenetic tree (Sok et al., 2013) (displayed horizontally) in complex with SOSIP trimer as determined from negative-stain EM reconstructions for Ab:SOSIP complexes. The correlation values were calculated by fitting the EM reconstruction of the 3H+3L:SOSIP.664-N137A complex into the corresponding reconstructions of the 32H+3L:SOSIP.664, PGT124:SOSIP.664, 9H+109L:SOSIP.664 and PGT122:SOSIP.664 complexes (please see Figure S2).
