What is ractopamine colloidal gold rapid detection card?

2025-08-18

Ractopamine, as a beta receptor agonist, has been used to improve the lean meat rate of livestock and poultry, but excessive residues will endanger human health, so it is crucial for the rapid detection of ractopamine in food. In this context, ractopamine colloidal gold rapid detection card came into being. It is a rapid detection product with colloidal gold immunochromatography technology as the core, which can complete the qualitative or semi-quantitative detection of ractopamine in samples in a short time.

From the working principle, this detection card utilizes antigen-antibody specific binding reaction. The colloidal gold in the card is labeled with ractopamine-bovine serum albumin conjugate. When the sample (such as pork, pig liver and other tissue homogenate extracts) is dropped into the sample well, it will move along the test strip. If ractopamine is present in the sample, it will compete with the colloidal gold marker to bind to the ractopamine monoclonal antibody on the detection line, resulting in a change in the color of the detection line to determine whether it contains the target substance.

Compared with traditional detection methods, the ractopamine colloidal gold rapid detection card has significant advantages. The first is fast speed, the whole detection process usually only takes 10-15 minutes, no need for complex instruments and equipment, and can be operated on site; the second is high sensitivity, which can detect ppb-level residues; furthermore, the operation is simple, no professional training is required, and ordinary personnel can complete it according to the instructions; at the same time, the cost is low, and it is suitable for large-scale screening.

In terms of application scenarios, the detection card is widely used in food production enterprises for raw material acceptance, processing process monitoring, rapid sampling by market supervision departments, and experimental research by scientific research institutions. It can help relevant parties to detect the risk of ractopamine exceeding the standard in a timely manner, effectively prevent food safety accidents, and protect consumers' dietary safety.

In short, ractopamine colloidal gold rapid detection card, with its fast, sensitive and convenient characteristics, has become an important tool for screening clenbuterol residues in the field of food safety, and plays an irreplaceable role in protecting public health.
