Abstract
ABSTRACTIn this study, a homologous multi-wavelength fluorescence polarization immunoassays (MWFPIA) for rapid determination of amantadine (AMD) and ribavirin (RVB) simultaneously was established. The MWFPIA could quantify AMD and RVB concentration simultaneously in 1 min. After optimisation, long-wavelength tracers AEDA-AF647 with monoclonal antibody (Mab) 1A12 and RVB-CP-EDF with polyclonal antibody (Pab) G412 were chosen for the development of MWFPIA. The limit of detections (LODs) of AMD and RVB were 1.7 and 1.0 μg/kg in chickens, and 17.6 and 10.4 μg/L in human serum, respectively. Recoveries of AMD and RVB in chickens were 61.2–94.9% and 87.3–90.2%, respectively with coefficient of variations (CVs) lower than 16.7%. For human serum, recoveries were 60.2–84.3% and 63.5–74.2% for AMD and RVB, respectively, and CVs was lower than 15.3%. The results indicated that the MWFPIA could be used for the monitoring of antiviral drugs with short analysis time, great accuracy and high throughput.
