Characterization of MAGP1 and VWF interactions using surface plasmon resonance. Different concentrations of von Willebrand factor were injected over MAGP1 immobilized on a BIAcore CM-5 sensor chip. Sensorgram shows 6 different analyte concentrations (0.052 μM, 0.105 μM, 0.21 μM, 0.32 μM, 0.42 μM, and 0.85 μM). One representative experiment is shown. The response difference (the difference between experimental and control flow cells) is given in resonance units (RU).
