(AC) QCM resonance frequency change (ΔF) profiles of either GST-ABD (black lines) or GST (red lines) on the gold QCM sensors and subsequent deposition of mouse (A), rabbit (B), and rat (C) IgGs on the monolayers of either GST-ABD (black lines) or GST (red lines). (DF) SPR sensorgrams of GST-ABD binding to IgG-immobilized gold SPR sensors (black lines) and the fitting curves (red lines) for the mouse (D), rabbit (E), and rat (F) IgGs.
