Principle and Application

This kit adopts the method of indirect competitive enzyme-linked immunoassay (ELISA) to detect Chloramphenicol (CAP) in the sample such as aquatic tissue, livestock tissue, liver, eggs, honey, milk, feed and water. The kit is composed of Microtiter Plate coated with coupled antigens, CAP-HRP enzyme conjugates, antibodies, standards and other supporting reagents. During the detection, with adding standards or samples, the CAP in the samples will compete with the coupled antigens to combine with anti-CAP antibodies. After adding enzyme conjugates, take coloration with TMB substrates. Absorbance value of the samples is a negative correlation with CAP content. Lastly, comparing with the standard curve, the obtained concentration is multiplied by the sample dilution ratio. CAP residues in sample can be concluded.
