Abstract: The CiELISA method for the detection of difloxacin were established with the polyclonal antibodies against difloxacin. The regression equation, the 50% inhibition concentration(IC50), the limits of detect (LOD) and the linear range about the standard curve of difloxacin were y=-0.223x+0.9631(r=0.9929), 119.21ng/ml,1.14 ng/ml and 1.14~10000 ng/ml, respectively. The average coefficients of variation for the CiELISA method were 4.83% in intraassay and 10.69% in interassay. The recoveries in chicken ranged from 81.24% to 90.64%.
