Under optimal conditions, this assay exhibited a working range of 0.0419 ng/mL, with half-maximum inhibition (IC50) and limit of detection values of 0.27 and 0.02 ng/mL, respectively. After three sample pretreatment procedures were checked, a simple dilution method was adopted for further use. The stabilisation studies demonstrated that the icELISA kits can be stored for at least 180 to 240 days, at 4\textdegreeC and 20\textdegreeC, respectively. When applied to bovine samples, the data from icELISA and gas chromatography coupled to mass spectrometry showed excellent correlation (r2=0.9923 in muscle, 0.9884 in liver and 0.9957 in kidney). Therefore, this assay has the potential to be incorporated into a quantitative monitoring programme for the rapid screening of TES residue in foods.", }
