The binding of a panel of monoclonal antibodies to V1, V2, and V3 loop-deleted HIV-1 gp120 was studied by competition analysis. Most of the previously defined relationships between gp120 epitopes were preserved on the variable loop-deleted protein, although interactions between some epitopes were dependent on the presence of the V1, V2, and V3 loops. Enzymatic deglycosylation of the variable loop-deleted protein only minimally altered the binding of most antibodies examined. Thus, a carbohydrate-deficient, conserved HIV-1 gp120 core can be produced that has a structure closely approximating that of the full-length, correctly folded gp120 monomer.
