ELISA for Rapid Screening of Clenbuterol Residues

The MaxSignal® Clenbuterol ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of clenbuterol and other related ß-agonists in feed, meat, liver, kidney, milk and urine.

Clenbuterol is one of major ß-agonists illegally used in livestock production. It can improve the meat-to-fat ratio in fattened animals and accelerate livestock growth. It also has a relaxing effect on non-striated musculature and can be used as an antiasthmatic and a tocolytic agent in human beings. Therefore, excess clenbuterol residues in livestock products may lead to health risks for consumers. This has led to a prohibition of clenbuterol use in food production. According to the US FDA and WHO, a maximum residue limit for clenbuterol is 0.2 ppb in muscle and fat, and 0.6 ppb in liver and kidney. The amount of clenbuterol residues can be determined by methods such as HPLC or GC-MS. However, these traditional methods usually require very expensive preparation procedures. Alternatively, enzyme immunoassay (ELISA) can be used as a screening system, which is simple, rapid, sensitive and cost-effective compared with traditional methods. 

This kit is manufactured to the international quality standard ISO 9001:2008.
