Binding specificity. (A and B) α5β1-Fc data are shown. (C and D) trα5β1-Fc data are shown. Frequencies of adhesion between 10 µg/ml FNIII7–10 adsorbed on cantilever tips and 10 µg/ml α5β1-Fc (A) or trα5β1-Fc (C) captured by 15 or 100 µg/ml GG-7 Fab precoated on Petri dishes in buffer containing the indicated cations without or with cyclo(-GRGDSP) or HFN7.1 in solution were enumerated in 100 tests for each spot and presented as mean ± SEM of 3–5 spots. Frequencies (measured with the same protocol as in A and C) of adhesion between 10 µg/ml FNIII7–10 coated on cantilever tips and 10 µg/ml α5β1-Fc (B) or trα5β1-Fc (D) captured by GG-7 Fab preadsorbed on Petri dishes with indicated concentrations (closed bars) are compared with those between BSA-coated tips and trα5β1-Fc–functionalized Petri dishes (open bars) and with those between FNIII7–10-coated tips and GG-7–coated Petri dishes without incubating with trα5β1-Fc (hatched bars) in the indicated cation conditions.
