FIG 1.

Efficient use of alternative sabaeus coreceptors with two sabaeus CD4 molecules by prototype SIVagmSab92018ivTF Env pseudotypes. 293T cells were transfected with sabaeus candidate coreceptors in conjunction with each of the two sabaeus CD4 alleles. Cells were infected 48 h later with pseudotypes carrying Env from the transmitter/founder SIVagmSab92018ivTF. Cells were then lysed 72 h later, and luciferase content was measured as relative light units (RLU). Infections were carried out in triplicate, and data (means ± standard deviations) are representative of results from 4 replicate experiments.
