The CDIATM Zeranol Colloidal Gold Test Cassette (Milk) is a lateral flow immunoassay for the detection of zeranol in milk.
Zeranol antigen is coated on the test region of the nitrocellulose membrane of the strips, and zeranol antibody is labeled with colloid gold. During a test, the colloid gold labeled antibody coated in the strip move forward along the membrane, and a red line will show up when the antibody gathers with the antigen in the test line; if zeranol in the sample is over the detection limit, line T is blank; on the other wise, if zeranol in the sample is less than the detection limit, line T is red.
Zeranol, or zearanol, also known as α-zearalanol or simply zearalanol, is a synthetic nonsteroidal estrogen of the resorcylic acid lactone group related to mycoestrogens found in fungi in the Fusarium genus and is used mainly as an anabolic agent in veterinary medicine. Zeranol may be found as a contaminant in fungus-infected crops. It is 3 to 4 times more potent as an estrogen than the related compound zearalenone. The CDIATM Zeranol Colloidal Gold Test Cassette (Milk) is a lateral flow immunoassay for the detection of zearalenin in milk.
