Athey D, Ball M, McNeil CJ: Avidin-biotin based electrochemical immunoassay for thyrotropin. Ann Clin Biochem. 1993 Nov;30 ( Pt 6):570-7.
A two site electrochemical enzyme immunoassay for thyrotropin (TSH) has been developed. This assay is based on the use of an immobilized capture antibody and a biotinylated second antibody. Detection is achieved via avidin labelled with alkaline phosphatase. The substrate 1-naphthyl phosphate was used and the product 1-naphthol was detected at disposable screen-printed carbon 8-electrode combs using specially designed instrumentation. |
