Comparison of time-resolved fluoroimmunoassay and immunoenzymometric assay for clenbuterol
Abstract
A time-resolved fluoroimmunoassay (TR-FIA) for the direct determination of clenbuterol residues in horse urine using a highly specific monoclonal antibody has been compared with an immunoenzymometric assay (IEMA). The sensitivity of both methods was 10 pg; the calibration curve was linear between 10 and 105 pg for the TR-FIA and between 10 and 104 pg for the IEMA.
