Abstract

Fluorescence polarization immunoassay (FPIA) is a convenient homogeneous assay, the use of which is restricted in environmental analysis by low sensitivity and matrix effects. We selected the herbicides 2, 4D and 2, 4, 5T to synthesize new l-lysine-based fluorescent tracers using solid-phase chemistry. In addition, three different immunogens of 2, 4, 5T were prepared for immunization and antibody production. The new tracers and antibodies were ...
