Recombinant Human Antibody (sAB) is capable of binding to GET3, expressed in HEK 293 cells. Expressed as the combination of a heavy chain (HC) containing VH from anti-GET3 mAb and CH1-3 region of human IgG1 and a light chain (LC) encoding VL from anti-GET3 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.
Figure 1 C) Single point competition ELISA - scatter plot showing ELISA signals of target binding (x-axis) and competition with soluble protein (y-axis) - clones located in top left corner of the plot (high ELISA 450 nm signal and low competition ratio; positive clone threshold - dashed line in gray) are picked for secondary screening (marked in blue).

Figure 2 D) SPR - affinity measurement; plot represents SPR trace of sAB injection (3 analyte concentrations) over 4 channels on a chip - binding is detected only when target protein (Abh3) is crosslinked to its ligand (DNA) - immobilized on channel 2 (blue lines), sABs do not bind to the reference channel or ligand alone and only residual binding (small signal change) is observed for protein without the ligand (red lines).
