Integrin antibody screening and assay development. (A) Staged efforts to screen integrin antibodies from human naïve IgG library by using Adimab’s yeast display platform. (B) IgG-expressing yeast clone selection process. The X-axis represents integrin binding and the Y-axis reflects antibody expression. Yeast cell population with strong antigen binding (boxed) was sorted out for the next round of selection. (C) Cell-based ELISA (CELISA) binding assays were used as the primary screen for integrin antibody selection. Dose-dependent binding of the benchmarking integrin antibody mAb-24 to various integrin-expressing CHOK1 cells was shown. (D) AlphaLISA integrin-ligand binding assays were used for in vitro functional screen. Dose-dependent inhibition of human integrin-ligand binding by MK-0429 in AlphaLISA assay panel.
