Recombinant Human Anti-HIV-1 gp120 Antibody (2G12) (CAT#: PABC-062)

Recombinant Human Antibody (2G12) 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 IgG1 and a light chain (LC) encoding VL from anti-HIV-1 gp120 mAb and CL of human kappa light chain. Exists as a disulfide linked dimer of the HC and LC hetero-dimer under non-reducing condition. This neutralizing human antibody recognizes terminal Man 1-2Man–linked moieties, contributed by oligomannose-type sugars that form a cluster on the silent face of gp120.

Inhibition of the binding of 2G12 mAb to HIV-1-infected MT-4 cells in the presence of GNA, HHA and CV-N. MT-4 cells infected with HIV-1 strains IIIB (left panel), MN (middle panel) and NDK (right panel), were incubated with 2G12 mAb in the absence (red histograms) or presence of different concentrations of GNA (green histograms), HHA (orange histograms) and CV-N (light blue). The dark blue histograms show the background fluorescence. The mean fluorescence intensity (MFI) values are indicated in each histogram.
