Quinolones device is for rapid test to qualitatively detect the Quinolones in milk sample. It only takes approx. 5~10 min.
The quinolones are a family of synthetic broad-spectrum antibi-otics. The term quinolone(s) refers to potent synthetic chemo-therapeutic antibacterials. They are widely used in different lines of poultry, cattle, agriculture and beekeeping for its excel-lent antibacterial and pharmacokinetic properties. However, man would suffer from Aplastic Anemia or agranulocytopenia if the hematopoiesis function of marrow is inhibited. What’s more, gastrointesinal tract and the nervous system will be affected. Therefore, it is possible that Chloramphenicol residues, after use in illegal practice, may lead to a risk for consumers.
PRINCIPLE OF THE TEST
Competitive assays are primarily used for testing small mole-cules. If Quinolones are present in the sample it will therefore bind with the conjugate and will be labelled. As the sample mi-grates along the membrane and reaches the capture zone an excess of labelled antibody will bind to the immobilised antigen so that no visible line is produced. The bound conjugate will then bind to the antibodies in the control zone producing a visible control line. A single control line on the membrane is a positive result. Two visible lines in the capture and control zones is a negative result. However, if an excess of unlabelled Quinolones are not present, a weak line may be produced in the capture zone, indicating an inconclusive result.
