Validation of cell clones resistant to HIV-1 infection with the reversibility assay. HIV-resistant RHGP Clone 1-13(A) and a naive RHGP Clone H6 (B) were challenged with HIV-1NL4-3 in the presence (RHGP "on") or absence (RHGP "off") of the ligand RSL1. Supernatants collected daily starting 3 dpi from these cell cultures were then examined for infectivity using TZM-bl cells and the results from 5 dpi are shown.
