Precipitation of HIV-1 gp120 mutants by the 412 antibody. Radiolabeled wtΔ or mutant derivatives were incubated with the 412d antibody in the absence (−) or presence (+) of sCD4 (8 μg/ml). The precipitated proteins are shown. The indicated conserved region (C1-C4) or the V3 region represents the location of the altered amino acid residue on the primary HIV-1 gp120 sequence.
