Recombinant Human Antibody (CNTO607) is capable of binding to IL13, expressed in HEK 293 cells. Expressed as the combination of a heavy chain (HC) containing VH from anti-IL13 mAb and CH1-3 region of human IgG and a light chain (LC) encoding VL from anti- IL13 proteins 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. CNTO607 binds human IL-13 with high affinity (Kd=15 pM) and prevents binding of IL-13 to both IL-13Rα1 and IL- 13Rα2. CNTO607 potently neutralizes the activity of IL-13 in a variety of bioassays, including cell survival, eotaxin production, and STAT6 signaling.
