Animal Tissue and Feed Illegal Additive Ractopamine ELISA Test Kit

Qualitative or quantitative analysis of ractopamine in swine urine, animal tissue, swine serum, feed and other samples.

Order No.: ME30AER


Ractopamine is a phenylethanolamine β2-adrenergic receptor agonist with a wide range of physiological effects. It is mainly used in the clinical treatment of bronchial asthma, congestive heart failure and muscular dystrophy. When the dosage is 5 to 10 times higher than the clinical dosage, it can regulate metabolism in the body, increase fat decomposition, promote protein synthesis, and show a nutrient redistribution effect. Adding it to the feed greatly improves the lean meat rate of livestock. When humans eat animal tissues containing ractopamine, it is very easy to produce toxic reactions such as rapid heartbeat, tremors, palpitations, etc., which will lead to teratogenic and carcinogenic human body.


Ractopamine ELISA Kit is an indirect competitive enzyme-labeled immunoassay. The ractopamine antigen is precoated on the wells. The precoated antigen compete the ractopamine antibody (Antibody Solution) with ractopamine in the sample, ractopamine antibody binds to the ractopamine Enzyme Conjugate. After the color development of TMB Substrate, the absorbance value of the sample is negatively correlated with the ractopamine contained in it. Compared with the standard curve and multiplied by its corresponding dilution factor, the content of ractopamine in the sample can be calculated.

Aflatoxin M1 Immunoaffinity Column

Order No.: QC0068,QC0069,QC0131,QC0071Column Capacity:100 ngVolumn: 3mLPackage: 25/50T 

Immunoaffinity Column for Aflatoxin B1,B2,G1,G2

The immunoaffinity column can selectively adsorb aflatoxins (B1, B2, G1, G2) from the sample solution, thereby purifying the sample. The purified sample solution can then be directly used for HPLC or LC-MS/MS analysis.Affinity columns can be used in combination with HPLC or LC-MS/MS to achieve rapid testing, and to increase signal-noise ratio  and improve the accuracy of the detection method.

Immunoaffinity Column for 2-in-1 Aflatoxins (B1,B2,G1,G2) and Ochratoxin A

The immunoaffinity column can selectively adsorb aflatoxin (B1, B2, G1, G2) and Ochratoxin A from the sample solution, thereby having a highly targeted purification effect on the sample. The sample  solution that has been purified by passing through the affinity column can be directly used for HPLC analysis or for LC-MS/MS analysis after concentrating with nitrogen gas and resuspended.Order No.: HCM3725B/HCM3750BProduct Properties: AFT B1/B2/G1/G2 300ng, OTA 100ngSpecifications: 3mL,25T/50T
