What is the Ologol Colloidal Gold Quick Detection Card?

Ologol Colloidal Gold Rapid Detection Card is an important rapid screening tool in the field of food safety testing. It is mainly used for qualitative or semi-quantitative detection of Ologol pesticide residues in food. As a highly toxic organophosphorus pesticide, Ologol has been widely used in agricultural production to control pests, but because its residues may cause harm to human health, it has become one of the key objects of food safety supervision.

The core principle of this detection card is based on colloidal gold immunochromatography technology. Colloidal gold is a commonly used immune marker with good stability and color rendering. The detection card contains key components such as Ologol antigens and colloidal gold-labeled antibodies. When the sample (such as the extract of vegetables, fruits, grains and other foods) is dripped into the sample hole of the detection card, it will move along the test strip under the action of capillaries. If the sample contains the residue of omethoate, it will bind to the antibody labeled with colloidal gold, prevent the antibody from binding to the antigen of the detection line (T line), resulting in no color development of the T line; conversely, if there is no residue in the sample, the antibody will bind to the T line antigen, so that the T line will develop color. By observing whether the C line (quality control line) is colored, it can be judged whether the detection card is valid, and then it can be judged whether the residue of omethoate in the sample exceeds the standard according to the color development of the T line.

Compared with the traditional detection method, the rapid detection card of omethoate colloidal The first is that the detection speed is fast, usually 10-15 minutes to produce results, which can meet the needs of on-site rapid screening; secondly, the operation is simple, no professional equipment and complex pretreatment are required, and ordinary personnel can get started with simple training; secondly, the cost is low, which is suitable for large-scale and normalized detection; at the same time, the accuracy and sensitivity can also meet the preliminary screening requirements, which can effectively identify high-risk samples, and provide a preliminary basis for subsequent accurate detection (such as gas chromatography, liquid chromatography, etc.).

In the application scenario, the detection card is widely used in the fields of raw material acceptance, processing process monitoring of food production enterprises, field rapid sampling and detection in the agricultural sector, market circulation food sampling inspection in the market supervision department, and experimental research in scientific research institutions. It can help regulators and producers detect the problem of Oloxan residue in food in time, control the risk from the source, and ensure the "safety on the tip of the tongue" of consumers. It is an indispensable and important tool in the current food safety rapid detection system.
