FIG. 5.
Contribution of anti-CD4-BS antibodies to plasma-neutralizing activities. Plasmas were incubated with beads coated with either WT gp120 or gp120 with a mutated CD4-BS. The flowthrough and the eluted antibodies were tested for neutralizing activity against HIV. (A and B) Sample from patient VC10042; (C and D) sample from patient VC10014; (E and F) sample from patient CC1161; (G and H) sample from VC10002. Flowthroughs (A, C, E, and G) and eluted antibodies (B, D, F and H) are shown. Nondepleted, neutralization curves obtained with unadsorbed plasmas; WT depleted, plasma flowthroughs from WT gp120; BS-mutant depleted, plasma flowthroughs from the CD4-BS mutant gp120.
