Twenty-five conformation-dependent monoclonal antibodies (MAbs) produced by immunization of mice with oligomeric forms of the human immunodeficiency virus type 1 (HIV-1) envelope (env) glycoprotein were used to map exposed, immunogenic regions on oligomeric env. Based on MAb cross-competition, reactivity with diverse env proteins, and reactivity with a panel of gp120 mutants, seven distinct epitope clusters were identified. These include the classic CD4 binding site, V1/V2, and V3. in addition, several novel epitope clusters, including one mapping to the N- and C-termini of gp120, were identified. The locations of the seven epitope clusters on the gp120 core structure are proposed.
