Test principle

This kit uses the principle of Colloidal Gold Immunochromatography assay. It can detect FQNs (Fluoroquinolones) in samples, such as honey, tissue, etc. After adding the sample solution into the sample well of detection card, FQNs of the sample solution combine with the gold-labelled antibody, so as to prevent the combining of gold-labelled antibody with FQNs conjugate on the cellulose membrane. When the concentration of FQNs in the sample solution is more than the detection limit, the detect line do not show color reaction and the result is positive. When the concentration of FQNs in the sample solution is less than the detection limit, the detect line shows purple and the result is negative.
