WebNoncompetitive immunoassays are designed to have excess antibody binding sites and produce a signal directly proportional to the amount of analyte in the sample. In sandwich immunoassays, two separate antibodies are used. A capture antibody is bound to a solid support and is used to extract the analyte of interest from the sample. WebPOTENTIOMETRY. Analyte must be present in the solution and touching the surface of the electrode. FUNDAMENTALS. We need TWO electrodes, because the open signal is POTENTIAL (V), we need the difference of potentials between the two electrodes. o One is the reference electrode and the other is the working/indicator electrode.
