FIG. 4.
Neutralization sensitivity of SHIVSF162P3N and SHIVBR24. The neutralization susceptibilities of the inoculating R5 SHIVSF162P3N (○) and emerging X4 SHIVBR24 (•) viruses to antibodies in sera from macaques CD80 and T799 (A) and CD4 binding site MAbs CD4-IgG2 and IgG1b12 (B) were determined as described in Materials and Methods. Data shown are representative of at least two independent neutralization experiments.
