Recombinant Human Antibody (F105) is capable of binding to HIV-1 gp120, expressed in HEK 293 cells. Expressed as the combination of a heavy chain (HC) containing VH from anti- HIV-1 gp120 mAb and CH1-3 region of human IgG and a light chain (LC) encoding VL from anti- HIV-1 gp120 proteins mAb and CL of human light chain. Exists as a disulfide linked dimer of the HC and LC hetero-dimer under non-reducing condition. F105 is a neutralizing, CD4–binding site (CD4BS) antibody, binding to gp120 occurred primarily through heavy-chain interactions, which were similar in many respects to those of CD4. F105 recognized conformational shifts in the position of the V1/V2 stem, resulting in a V1/V2 orientation poorly compatible with the functional viral spike.

(C) Western blot analysis of immunoprecipitated 4-2.J41 Env protein from plasmamembrane fraction. Proteins from the plasma membrane fraction of Env transfected 293T cells were immunoprecipitated with VRC01, PGT151 and F105 antibodies and analyzed by Western blot using HIVIG as probe.
