Binding of MoAb anti-LIBS6 (10 μg/mL) induced by ADP (20 μmol/L), c7E3 (10 μg/mL), and GRGDSP (2 mmol/L) or no addition. Binding of MoAb anti-LIBS6 was detected by an FITC-labeled, polyclonal Fc-fragment-specific anti-IgG mouse Ab. Background binding with unspecific MoAb has been subtracted. Results are depicted as the mean of three determinations ± standard deviation. Using the unpaired Student’s t-test, P values less than .02 were obtained for comparisons between no addition and the addition of ADP, c7E3, and GRGDSP, respectively.
