A simple and rapid method of fluorescence polarization immunoassay (FPIA) for detection of Alternaria mycotoxin tenuazonic acid (TeA) was described. In this study, the tracers TeAH-FITC and TeAH-DTAF were synthesized from hapten 5-(sec-butyl)-3-(1-hydrazonoethyl)-4-hydroxy-1H-pyrrol-2(5H)-one (TeAH) and different fluoresceins isothiocyanate isomer I (FITC) or 5-([4,6-dichlorotriazin-2-yl]amino)fluorescein...
A heterologous competitive indirect enzyme-linked immunosorbent assay (ciELISA) for the determination of the furaltadone metabolite 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ) was developed. AMOZ was derivatised with 2-(4-formylphenoxy) acetic acid or 2-(3-formylphenoxy) acetic acid to obtain two novel immunizing haptens. The ability of these haptens in producing specific polyclonal antibodies...
Immunoassay for low molecular weight food contaminants, such as pesticides, veterinary drugs, and mycotoxins is now a well-established technique which meets the demand for a rapid, reliable, and cost-effective analytical method. However, due to limited understanding of the molecular structure of antibody binding sites and antigenic epitopes, as well as the intermolecular binding forces that come into...
