Audited Supplier 1. Background
Ractopamine belongs to β-agonists family. β-agonist is a class of nutrient repartitioning agents, which is a phenylethanolamine ramification structurally and functionally similar to adrenalin and noradrenalin, it can promote animal growth, decrease body fat content and improve lean meat percentage. It has been prohibited to promote animal growth in EU. Ractopamine is a nonprescription drug, which is much cheaper than CLA, thus it is being illegally used quite often in animal production.
This kit is a new product based on ELISA technology, which is fast, easy, accurate and sensitive compared with common instrumental analysis, so it can considerably minimize operation error and work intensity.
2. Test Principle
This kit is based on indirect-competitive ELISA technology. The microtiter wells are coated with coupling antigen. Ractopamine residue in the sample competes with the antigen coated on the microtiter plate for the antibody. After the addition of enzyme conjugate, chromogenic substrate is used to show the color. Absorbance of the sample is negatively related to the ractopamine reside in it, after comparing with the Standard Curve, multiplied by the dilution factor, ractopamine residue quantity in the sample can be calculated.
3. Applications
This kit can be used in quantitative and qualitative analysis of ractopamine residue in urine, tissue(muscle, liver), feed and serum.
4.Detection limit:
Urine...........................…0.1ppb
Tissue..................….......….0.3ppb
Feed...........................…....3ppb
Serum.............................0.1ppb
