What is the Prochloramine and Prochloramine Manganese Salt Colloidal Gold Rapid Detection Card?

In modern agricultural production, prochloramine and prochloramine manganese salt, as efficient and broad-spectrum fungicides, are often used to keep fruits and vegetables fresh, prevent and treat diseases, and effectively improve the yield of agricultural products. However, excessive residues may endanger human health, so rapid and accurate detection methods have become the key to food safety supervision. At this time, prochloramine and prochloramine manganese salt colloidal gold rapid detection card came into being, providing a new option for pesticide residue screening.

So, what exactly is this kind of detection card? It is based on colloidal gold immunochromatography technology and realizes detection through the principle of specific binding of antigens and antibodies. The detection card contains components such as colloidal gold-labeled prochloramine antibody, nitrocellulose membrane (coated with prochloramine-carrier protein conjugate as the detection line, and the quality control line is sheep anti-mouse IgG) and sample pad. When the sample (such as fruit and vegetable extract) is dropped into the sample well, it will move along the chromatography strip. If the sample contains prochloramine or prochloramine manganese salt, it will compete with the colloidal gold-labeled antibody to bind the antigen on the detection line, resulting in the color of the detection line becoming lighter or disappearing, so as to determine whether there is residue.

Compared with traditional detection methods (such as high-performance liquid chromatography, gas chromatography, etc.), the colloidal gold rapid detection card has significant advantages: the detection time is short, usually 10-15 minutes to produce results; the operation is simple, no professional equipment and complex pretreatment are required, and ordinary personnel can get started after simple training; low cost, suitable for batch screening; high sensitivity, can reach the detection limit of μg/L level, and meet the requirements of agricultural product safety standards.

At present, this type of detection card is widely used in agricultural production bases for rapid field screening, wholesale market entry testing, and catering enterprises for raw material checkpoints. It can detect excessive products in a timely manner, control the risk of pesticide residues from the source, and build a strong line of defense for consumer table safety. With the continuous optimization of technology, the colloidal gold rapid detection card is developing towards higher sensitivity and more portability, and will play a greater role in food safety supervision in the future.
