Inhibition of SF162 and YU.2 HIV-1 infectivity by differentially glycosylated recombinant gp120. SF162 or YU.2 pseudoviruses (200 TCID50) together with serially diluted gp120 preparations (1 to 0.015 μg/well) were added to TZM-bl reporter cells, and 48 h later luciferase activity was measured in the cell lysates. Results are expressed as % inhibition of the infection of TZM-bl reporter cells, with pseudovirus alone considered 100% infection. Data from three independent experiments are shown.
