Abstract

A new amperometric immunosensor for detection of antibodies against bovine leukemia protein (gp51) was designed. The detection of antibody-antigen complex formation was based on application of secondary antibodies labeled with horseradish peroxidase (HRP). Ferrocenecarboxylic acid (FCA) and N,N,N',N'-tetramethylbenzidine (TMB) were selected as suitable mediators for this immunosensor. Optimal conditions for amperometric detection were found. Sensitivity of created system was compared with the results of enzyme-linked immunosorbent assay (ELISA) and agar gel immunodiffusion (AGID) reaction, and was sufficient for detection of usual anti-gp51 antibody concentration present in the blood serum of BLV-infected cattle.
