VERFAHREN ZUR BEURTEILUNG VON ZIELMOLEKÜLEN

摘要

A method for evaluating a target molecule 7 bound to a probe molecule 1 provided with a marker 3 includes: applying an AC voltage between a working electrode 2 provided on a substrate and a counter electrode 8, and using a signal obtained from the marker on the probe molecule bound to the working electrode when a frequency of the AC voltage is varied, or an average value of the signal, to determine a Stokes radius or molecular weight of the target molecule, a binding rate between the probe molecule and the target molecule, or a binding rate constant therebetween, a dissociation rate therebetween, or a dissociation rate constant therebetween.
