IMPROVEMENT OF SENSITIVITY OF ELECTROCHEMICAL MEASUREMENT OF REDOX KIND-MODIFIED ANTIBODY USING COMB-SHAPED ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a method for improvement of sensitivity of an electrochemical measurement of a redox kind-modified antibody using a comb-shaped electrode for suppressing, by simple and easy operation, current decrease due to adhesion of an antibody to an electrode, and decrease of current value caused by decrease of redox cycling efficiency.;SOLUTION: A comb-shaped electrode 101 formed by applying a water-soluble polymer compound onto the surface of an electrode system and drying it is employed, so as to prevent current decrease due to adhesion of an antibody and decrease of redox cycling efficiency, to obtain a high current value.;COPYRIGHT: (C)2013,JPO&INPIT
