Abstract: Adifferential pulse voltammetric immunoassay associated with the TMB-H2O2-HRPfor the determination of IgEantibody was developed. The enzymatic reaction product produced by HRPcatalyzing the oxidation of H2O2 with TMBexhibits a sensitive voltammet-ric response at 0.10V(vs.Ag/AgCl) in pH 4.0 phosphate-citrate buffer solution. The de-tection limit of the present method for IgEantibody was 4.0IU/mL, which was four times lower than that obtained by traditional spectrophotometric ELISAprocedure. It has been ap-plied to the determination of IgEin human serum with satisfactory results.

Key words: 3,3',5,5'-Tetramethylbenzidine (TMB), IgE, ELISA, Differential pulse voltammetry
