• Product Details

  1. Brief This product is used for testing Aflatoxin B1 residue in grain, peanut, feed and edible oil sample, suitable for on-site rapid test. Easy to operate, high sensitivity. 2. Detection limit 2.5ng/g (2.5ppb) ~50ng/g (50ppb) 3. Specifications: 50 tests/kit 4. Principle The Aflatoxin B1 rapid test strip is an immuno-chromatographic test, using colloidal gold immunoassay method. It relies on the competition between Aflatoxin B1 residues in the sample and? the Aflatoxin B1 on T line, to the limited amount of dye-antibody. As a sufficient amount of drug in the sample is presenting, the drug will saturate the antibody. Consequently, it will show an extremely light or even invisible T line, indicating a positive result. On the other hand, if there is a negative sample (or the amount of the drug is lower than the minimum detectable concentration), it will generate two obvious lines in both the T and C line section. 5.
