What is the rapid detection card for amoxicillin (β-lactam) colloidal gold in poultry eggs?

As an important source of nutrients in the daily diet, the safety and quality of eggs are directly related to the health of consumers. In recent years, with the widespread use of antibiotics in the breeding process, the problem of drug residues that may appear in poultry eggs has attracted much attention. Among them, the abuse and residue of beta-lactam antibiotics (such as amoxicillin) are the focus of food safety supervision. In order to quickly and accurately screen the residues of amoxicillin in poultry eggs, the rapid detection card for amoxicillin (beta-lactam) colloidal gold in poultry eggs came into being and has become an important tool in the field of egg safety detection.

So, what is the rapid detection card for amoxicillin colloidal gold in poultry eggs? In simple terms, it is a rapid detection product based on colloidal gold immunochromatography technology, which is mainly used for qualitative or semi-quantitative detection of β-lactam antibiotics (especially amoxicillin) in poultry eggs (such as eggs, duck eggs, etc.). Its core principle is to use antigen-antibody specific binding reaction: detect the card containing amoxicillin-carrier protein conjugate (as a detection line) and colloidal gold-labeled amoxicillin antibody (as a binding pad). When the sample (e.g. egg homogenate extract) is dropped into the detection card and sample hole, it migrates upward under capillary action. If there is amoxicillin residue in the sample, it will bind to the colloidal gold-labeled antibody and prevent it from moving to the detection line. If there is no residue in the sample, the antibody will bind to the antigen of the detection line to form a red band to determine the detection result.

, as a rapid detection product, has significant advantages: first, the detection speed is fast, usually 10-15 minutes to produce results, without the need for complex equipment and professional operation, suitable for on-site or grass-roots rapid screening; second, the operation is convenient, only simple sample pretreatment (such as dilution, centrifugation) and sample addition steps, ordinary personnel can master after short-term training; third, the cost is low, compared with high-performance liquid chromatography and other large-scale instrument detection, can greatly reduce the detection cost, suitable for batch sample screening; fourth, the accuracy is high, and its detection sensitivity and specificity have been strictly verified, which can effectively distinguish between positive and negative samples, providing reliable data support for regulatory authorities.

In practical applications, the rapid detection card of amoxicillin colloidal gold in poultry eggs is widely used in raw material control of poultry egg production enterprises, market sampling inspection in the circulation link, food safety screening in the catering industry, and daily monitoring by government regulatory departments. Through this test card, the problem of amoxicillin residues in poultry eggs can be detected in time, the flow of unqualified products into the market can be reduced, and consumers' "safety on the tip of the tongue" can be guaranteed from the source.

With the increasing attention of consumers to food safety, the rapid detection card of amoxicillin colloidal gold in poultry eggs is gradually becoming an important choice for egg safety testing due to its fast, convenient and efficient characteristics, and contributes to building a safer food supply chain system.
