a) AIF associates with a randomized DNA sequence bound to the biosensor surface in a pH dependent fashion. The pH chosen for further assays was 6.3, the pH at which AIF exhibits moderate PWV shifts and is stable over the course of the assay. b) Increasing AIF concentrations (0–51.7 μM) causes a dose-dependent shift increase in the PWV shift. c) Preincubation of AIF (7.02 μM) with a nonbiotinylated randomized DNA sequence inhibits the interaction of AIF with the DNA bound sensor surface. All error bars represent the calculated standard error (n = 3).
