Abstract
The detection of an antibody against nucleoprotein (NP) of the avian influenza virus (AIV) was attempted by an electrochemical immunoassay by combining a secondary antibody-alkaline phosphatase conjugate and 4-aminophenylphosphate. Released 4-aminophenol was quantitated electrochemically, and the current derived from oxidation of the hydrolysis product increased linearly over a wide primary antibody concentration range (10–1000 ng/ml). The detection limit of this electrochemical immunoassay for the antibody against the NP of AIV was found to be 10 ng/ml.
