Paper Title:
Development and Optimization of a mAb-Based Indirect Competitive ELISA for Enrofloxacin Residue in Duck
  Abstract

This paper presents the generation of monoclonal antibodies (mAbs) with high specificity against enrofloxacin (ENR) through cell fusion procedures, and the development of a mAb-based indirect competitive ELISA (icELISA) method to detect ENR residue using one of these Hybridomas (clone 4B5-D6). Under the optimal experimental conditions, this assay exhibited a working range of 0.004-38 ng/mL with IC50 and LOD values of 0.4 and 0.002 ng/mL, respectively. Except for a high cross-reactivity (105.2%) to Ciprofloxacin, negligible cross-reactivity to the other compounds was observed. After optimization, 10% of methanol was used in the assay buffer and this ELISA system can tolerate acetonitrile not higher than 10%. Recovery studies indicate that an excellent correlation between concentration spiked and concentration determined was found, and the results also suggest this assay has the potential to be incorporated into a quantitative monitoring program for the rapid screening of ENR residue in poultry tissues.
