title: A highly specific detection method for diethylstilbestrol in bovine urine by radioimmunoassay following high performance liquid chromatography.
abstract: A specific radioimmunoassay (RIA) for diethylstilbestrol (DES) is presented following purification of sample extracts by isocratic reversed phase high performance liquid chromatography. Applications are given of a forensic investigation for the control of DES in bovine urine. Specificity of HPLC-RIA is compared with that of RIA's with other (chromatographic) purification procedures and with gas chromatography-mass spectrometry. Implications of the use of these techniques in practice and the use of various DES-antisera are discussed.
