Relative affinities of LigB proteins for fibronectin and fibrinogen.

aApparent dissociation constant estimated by ELISA. Mean and standard deviation from at least three separate experiments is shown, except where the mean from two experiments is shown with the range in parentheses; n.d., not determined. bRelative affinity compared to LigB7′-12; where 100% is shown, the affinities are statistically equivalent. cSignificant 2.9-fold enhancement by repeat 11 (P<0.01). dSignificant 8.1-fold enhancement by repeat 11 for fibronectin binding (P<0.001), and 6.3-fold stimulation for fibrinogen binding (P<0.001). eSome dependence on repeats 7′ and 8 in the absence of repeat 11, giving a 3.3-fold effect (P<0.001).
