What is the Salbutamol Colloidal Gold Rapid Detection Card?

What is the Salbutamol Colloidal Gold Rapid Detection Card? This is a rapid detection tool specially designed for the detection of salbutamol residues. Based on the colloidal gold immunochromatography technology, it can perform qualitative or semi-quantitative analysis of the salbutamol content in food in a short time.

From the definition point of view, its core is "fast" and "accurate". As a just-in-time detection (POCT) product, its detection process does not require complicated equipment. It only needs to react the sample with the detection card. By observing the color rendering results, it can determine whether there is a salbutamol residue. The result can be obtained in 10-15 minutes, which greatly shortens the waiting time of traditional detection methods.

Looking at the technical principle, the detection card contains key components such as the colloidal gold-labeled albuterol antibody, nitrocellulose membrane (coated with albuterol-carrier protein conjugate and quality control line antibody). When the sample is dropped into the sample well, it moves forward under the action of capillaries. If the sample contains albuterol, it will bind to the colloidal gold-labeled antibody to form a complex; if there is no albuterol in the sample, the antibody will continue to move to the detection line, bind to the coated antigen, and develop color on the detection line and quality control line. The result can be judged by observing whether the two lines are colored - two lines are negative and one line (only the quality control line is colored) is positive.

Its advantages are very prominent: simple to operate, no professional training is required, and ordinary personnel can complete it according to the instructions; low cost, compared with large-scale instruments such as high-performance liquid chromatography, the test card is affordable and suitable for batch testing; Portability is strong, small size, and can be used for on-site testing outside the laboratory, such as in farms, slaughterhouses, market sampling and other scenarios.

In the application scenario, the Salbutamol Colloidal Gold Rapid Detection Card is mainly used in the field of food safety supervision to help relevant departments quickly screen meat (such as pork, beef), aquatic products (such as fish, shrimp) and other foods for salbutamol residues, prevent "clenbuterol" excessive products from entering the market, and ensure consumer dietary safety. At the same time, food production enterprises can also conduct raw material self-inspection through it to control the quality of production links.

Simply put, the Salbutamol Colloid Gold Rapid Detection Card is the "rapid screener" in the field of food safety testing. With its fast, convenient and economical characteristics, it plays an important role in guarding the safety of the dining table.
