Rapid quantitative testing kits for Ochratoxin A
Determination of corn Ochratoxin A in grain, grain products, nuts, wine, beverage, feed raw materials and feed
Ochratoxin is another mycotoxin that has attracted worldwide attention after aflatoxin. Ochratoxin A is a group of important mycotoxins produced by 7 species of Aspergillus and 6 species of Penicillium, which pollute food. Among them, ochratoxin A is the most toxic, the most widely distributed, the highest yield, the most serious pollution to agricultural products and the most closely related to human health.
1. Kit description
This product is a colloidal gold rapid detection card for ochratoxin A, which is used for quantitative detection of ochratoxin A residues in grain and its products.
2. Principle of kit
Based on competitive colloidal gold technology, there are two invisible lines sprayed on the central white film surface of the detection card, the top one is QC line C line and the next one is the detection line t line; If ochratoxin A is not contained in the sample, the antibody colloidal gold complex of ochratoxin A on the reaction card will be mostly captured by T-line and will show obvious color; If the sample contains ochratoxin A, the color of T-line will become light or disappear with the increase of ochratoxin a concentration. The detection line is light and dark by card reader. According to the light color and the standard curve built in the card reader, the content of ochratoxin A in the sample is calculated automatically.
