[Enzyme immunoassay for determination of sulfamethoxypyridazine in honey].

ABSTRACT

An enzyme immunoassay technique for the detection of sulfamethoxypyridazine in honey, developed using rabbit polyclonal antibodies raised against N-sulfonyl-4-aminobutyric acid, which contains a structural group characteristic of sulfonamides, is proposed. Under the optimized conditions, the sulfamethoxypyridazine detection limit was 0.05 ng/ml, with the entire analysis procedure taking 2 h. In total, 24 honey samples were tested using the protocol based on tenfold dilutions of samples without their preliminary treatment.
