  • Method of measuring glycosylated protein proportion by AC impedance method
    Patent number: 9080939
    Abstract: A method of measuring a glycosylated protein proportion by an AC impedance method includes passing an AC voltage or AC to two inspecting electrodes; covering a solution containing glycosylated protein completely onto the inspecting electrodes; measuring an impedance value between the electrodes and calculating the difference between the impedance value and an impedance value of a solution without glycosylated protein by an AC impedance inspection device; comparing the impedance difference with AC impedance difference/glycosylated protein concentration to obtain the proportion of the glycosylated protein in the solution containing glycosylated protein.
    Type: Grant
