FIG. 2.
Inhibition of MAb binding to oligomeric Env expressed on the surface of HIV-1MN-infected cells. Cells were preincubated with various concentrations of DexS (A) or ATA (B) before being washed, and gp120-specific MAbs were added. Bound MAb was detected by indirect immunofluorescence and flow cytometry, and the results are expressed as percent inhibition of MAb binding relative to the positive (no inhibitor) and negative (no MAb) controls. Each datum point is the mean of values for triplicate samples.
