摘要： To establish a highly sensitive chemiluminescent enzyme-linked immunosorbent assay (ci-ELISA) method for the determination of florfenicol (FF) in egg and chicken meat. Based on the obtained monoclonal antibodies against florfenicol, a chessboard test was employed to determine the optimal working concentration of artificial antigen and antibody, and then established a ci-ELISA method, and characterized its performance. The results showed that the ci-ELISA method had a detection limit of 5.433 pg/mL, an IC50 of 30.893 pg/mL, and a detection range between 5.433 and 193.577 pg/mL. The coefficient of variation was below 10%, indicating satisfactory precision. The spiked recoveries in egg samples were between 90.03% and 95.24%, and the spiked recoveries in chicken meat samples were between 90.56% and 93.04%. In conclusion, the developed ci-ELISA method is highly sensitive and suitable for monitoring and detection of trace amounts of FF residues in eggs and chicken meat.
