The fluorescence microscopic image of one of the selected ‘hit’ beads that binds only to PAE/KDR cells (10 × magnification; DAPI filter). The arrow indicates the red cells bound bead, while the majority of the surrounding beads do not have any cells bound, indicating the cleaner identification of the ‘hit’ bead (Reprinted with permission from UDUGAMASOORIYA, D.G., DINEEN, S.P., BREKKEN, R.A., KODADEK, T; A PEPTOID “ANTIBODY SURROGATE THAT ANTAGONIZES VEGF-VEGF RECEPTOR 2 INTERACTION, J.
