摘要
Using immunological and cell fusion technology, group-specific monoclonal antibodies were produced against cyproheptadine. The 50% inhibitory concentration of the antibody for cyproheptadine was 0.37ng/mL, the linear range was 0.16-0.85ng/mL, and recoveries of antibody in spiked negative pig urine were 80-120%. An ultrasensitive immunochromatographic strip, based on the antibody, was developed for the rapid detection of cyproheptadine in pig urine. The test strip had a cut-off value of 5ng/mL.
