Recombinant Human Anti-IAV HA Antibody (CT149) (CAT#: PABL-213)

Recombinant Human Antibody (CT149) is capable of binding to IAV HA, expressed in HEK 293 cells. Expressed as the combination of a heavy chain (HC) containing VH from anti-IAV HA mAb and CH1-3 region of human IgG1 and a light chain (LC) encoding VL from anti-IAV HA 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 antibody is found to neutralize all tested group 2 and some group 1 influenza A viruses by inhibiting low pH-induced, HA-mediated membrane fusion.

ELISA analysis of PABL-213 was performed by coating with Influenza A H3N2 (A/Perth/16/2009) Hemagglutinin / HA Protein (His Tag). Then blocked with BSA and incubated with PABL-213. The HRP-conjugated goat anti-Human IgG as a secondary antibody (1: 2000). Detection was performed using TMB substrate and stopped with sulfuric acid. The absorbances were read on a spectrophotometer at 450 nm.

Western blot analysis of PABL-213 was performed with Influenza A H3N2 (A/Perth/16/2009) Hemagglutinin / HA Protein (His Tag) onto a 12% Tris-HCl polyacrylamide gel. Proteins were transferred to a CN membrane and blocked with 5% skim milk for at least one hour. Membranes were probed with PABL-213 and HRP goat anti-Human IgG as a secondary antibody (1: 2000). Chemiluminescent detection was performed.
