ELISA for Screening of Beta Agonist Residues in Food

The MaxSignal^® Beta-Agonist ELISA Test Kit is a competitive ELISA for the quantitative analysis of clenbuterol, salbutamol, bitolterol, carbuterol and other related beta-agonists in a variety of sample types. Beta-agonists can improve the meat-to-fat ratio in fattened animals and accelerate livestock growth. They also have a relaxing effect on non-striated musculature and can be used as antiasthmatic and tocolytic agents in human beings. Therefore, excess beta-agonist residues in food products may lead to health risks for consumers. This has led to a prohibition of beta-agonist use in food production. The amount of beta-agonist 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.
