Abstract
Immunoassays featuring voltammetric measurements wherein at least one of the immunoreactants is labelled with an electroactive substance. Measurement is effectedon a pulsed-basis to maximize the signal change due to the electron transfer capabilities of the labelled immunoreactants.
Claims8
A voltammetric monitoring electrode for measuring electrochemical changes resulting from an immunoreaction between complementing immunoreactants, said voltammetric monitoring electrode comprising an electroactively-labelled immunoreactant attached to a surface thereof.
An electroactively-labelled immunoreactant having more than one electroactive group attached thereto for the purpose of increasing the ability of the immunoreactant to transfer electrons at a surface of a monitoring electrode during a voltammetric immunossay, and hence, increase the sensitivity of measurement of said immunoreactant.
