1 Scope

This standard specifies four methods of enzyme-linked immunosorbent assay nitrofuran metabolites residues in food of animal origin exports. This standard applies to chicken, pork, crawfish, back to the fish, milk, honey and other food of animal origin furazolidone metabolite (AOZ), furan It is one metabolite (AMOZ), nitrofurazone metabolite (SEM), nitrofurantoin metabolite (AHD) residues detected. Principle 2 Determination of the basis of this method is a competitive enzyme immunoassay, the overall process includes four nitrofuran metabolites residues detected. in Microtiter plates pre-coated strips and conjugate antigen in the sample nitrofuran metabolites residues after derivatized and even pre-coated on the strips are of Associated antigen antibody anti-competitive corresponding derivatives of nitrofuran metabolites after adding enzyme-labeled secondary antibody with TMB chromogenic substrate, the sample absorbance value Its content contained nitrofuran metabolites residues negatively correlated with the standard curve and multiplied by the corresponding dilution factor can be derived sample The remaining amount of nitrofuran metabolites residues.
