FIG 2.

Neutralization ID₅₀ titers of plasma (reciprocal dilutions) from 13 viremic SHIV_SF162P3N-infected rhesus macaques against 4 homologous SHIV Env pseudoviruses (top) and 10 HIV-1 Env pseudoviruses (bottom), as indicated. The dashed horizontal lines indicate the tested limit of 1:25 dilution; resistant values (<25) are plotted between 11 and 20. The blue symbols in the top diagram indicate autologous responses, as animals EE29 and FF59 were infected with the SHIV_SF162P3N inoculum-derived molecular clones 8 and 11 and animals FD83 and FF94 were infected with clone 8. Each animal was tested at two time points. wpi, weeks postinfection.
