Biospecific interaction analysis in real time between p97 and various anti-p97 mAbs. p97 was immobilized on a sensor chip (CM5) using standard coupling procedures incorporating NHS, EDC, and ethanolamine. Different mAbs directed against p97 (HybC, HybE, HybF, L235, 2C7, 9B6), diluted to 0.05 μg/μL in Ringer-HEPES, were injected into the BIAcore at a flow rate of 5 μL/min. The surface plasmon resonance response obtained for these mAbs was plotted (in relative units [RU]) as a function of time. After each injection, immobilized p97 was regenerated with 0.2M glycine at pH 2 for 2 minutes followed by a 2-minute injection of ferric ammonium citrate (1 mM) (n = 4).
