The Most Sensitive Ractopamine ELISA Available
The MaxSignal® Ractopamine ELISA Test Kit is designed for routine screening of ractopamine in meat, animal tissue, milk, feed, urine, serum, and plasma. The novel, proprietary sample extraction protocol incorporated into this kit enables the detection of as little as 0.1 parts per billion (ppb) of ractopamine in meat samples, a concentration well below the 1 ppb minimal required performance limit (MRPL) used by countries which have banned this substance.
This kit is manufactured to the international quality standard ISO 9001:2008.
Approved for use with the USDA’s Never Fed Beta- Agonists Marketing Program
The MaxSignal Ractopamine ELISA Test Kit has been approved by the USDA to be used for the verification testing requirements for screening of meat in the Never Fed Beta- Agonists Marketing Program. Here is a list of the AMS‐approved test methods which have been approved as verification methods for contamination with beta agonists residues.
Selected Publications that Reference the use of the MaxSignal Ractopamine ELISA Test Kit:
Chen, R. et al. (2011) Rapid Detection of Ractopamine Residues in Imported Porcine Products. Journal of Chinese Veterinary Medicine, 45 (8); 20-23, 2011.
Ractopamine is banned for use as a livestock growth promoter in many regions and countries, including Europe and China. To prevent ractopamine residues entering the food chain, both producers and government surveillance agencies need technologies and methods that can provide rapid, accurate and reliable results at the required sensitivity.
