Preparation of a monoclonal antibody against amantadine and rimantadine and development of an indirect competitive enzyme-linked immunosorbent assay for detecting the same in chicken muscle and liver

Publication date: 30 January 2017 Source:Journal of Pharmaceutical and Biomedical Analysis, Volume 133 Author(s): Dapeng Peng, Wei Wei, Yuanhu Pan, Yulian Wang, Dongmei Chen, Zhenli Liu, Xu Wang, Menghong Dai, Zonghui Yuan A monoclonal antibody (mAb) was produced in order to monitor the illegal use of amantadine and rimantadine in animals. The produced mAb 2G3 exhibited an IC50 value of 15.8μgL−1 for amantadine and exhibited cross-reactivity to both amantadine (100%) and rimantadine (70.6%). Standard curves ranged from 5 to 80μgL−1 for 2G3. The limits of detection of the developed indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) ranged from 5.0μgkg−1 to 5.4μgkg−1 in chicken muscle and liver. The recoveries were 81.3% to 98.1% with a coefficient of variation less than 15.7%. Good correlations were observed between the results of the ic-ELISA and liquid chromatography-mass spectrometry in the incurred tissues. These results suggest that ic-ELISA is a sensitive, accurate, and low-cost method that could be a useful tool for screening the residues of amantadine and rimantadine in chicken muscle and liver.
