Recombinant Human Antibody (9H+3L) is capable of binding to HIV-1 env, expressed in HEK 293 cells. Expressed as the combination of a heavy chain (HC) containing VH from anti-HIV-1 env mAb and CH1-3 region of human IgG1 and a light chain (LC) encoding VL from anti-HIV-1 env mAb and CL of human light chain. Exists as a disulfide linked dimer of the HC and LC hetero-dimer under non-reducing condition.
Figure 1 Neutralization assays on JR-FL glycan mutants indicate binding of inferred intermediate antibodies to both N301 and N332 on HIV-1 Env.
(A) Neutralization curves of inferred intermediate antibodies on wild-type JR-FL virus (B) JR-FL N301A mutant virus, and (C) JR-FL N332A mutant virus. (D) Neutralization curves of 3H+3L and (E) PGT121 on wild-type JR-FL virus compared to single and double glycan mutant viruses. (F) Neutralization curves of PGT121 on wild-type 92BR020 virus compared to single and double glycan mutant viruses.
