Intended Use
To be used in combination with the Nitrofurans Accessory kit, for the quantitative in vitro determination of Furazolidone (i.e. AOZ) in a test sample i.e. tissue (prawn, beef, pork and poultry).
General Background
The Nitrofurans are a class of antibiotics widely used in veterinary medicine to treat pigs, poultry, fish and shrimp. Bans on nitrofurans were introduced within the EU primarily because of concerns about their carcinogenicity and mutagenicity. Several other non-European countries have also banned all uses of nitrofurans in food producing animals.
Tissue residue of Furazolidone is mainly protein bound, therefore the main metabolite 3amino-2-oxazlidinone (AOZ) is proposed as the marker residue.
This ELISA provides a fast, reliable, analytical method to detect the presence of AOZ. If performing the test using duplicate wells, this kit has the ability to analyse 40 samples per plate.
Principle
Each microtitre plate is supplied precoated with an AOZ antibody. AOZ (antigen) in the Nitrofuran standard (multi antigen) and, if present, in the sample competes with the horseradish peroxidase labelled AOZ in the Nitrofuran multi conjugate for a limited number of antibody sites on the microtitre plate. After incubation at room temperature, to allow a competition reaction to take place, the microtitre plate is washed to remove excess reagents.
The enzyme substrate is added. After an incubation period to allow maximum colour development, the colour reaction is stopped by the addition of acid. This produces a colour change from blue to yellow, and the absorbances are read at 450nm.
A standard curve is then constructed to determine the AOZ concentration in the sample.
