Surface to which a antibody is immobilised
WebDec 31, 2014 · Comparison of AFM image of antibody coated surface where the AFM imaging was done at ( A) 0° and ( B) 90° with respect to the direction of the originally applied 8 V/cm electric field during the IgG immobilization step. This illustrates that the observed orientation of molecules is not due to AFM stamping artifact. Open in viewer WebThis antibody-modified surface was able to capture human CRP protein, and the impedance signal showed linear dependence with CRP concentration. We confirmed the immobilization of anti-CRP mAb using surface sensitive X-ray photoelectron spectroscopy (XPS) and electrochemical impedance.
