The CDIATM Ochratoxin A Colloidal Gold Test Cassette (Grain/Feed) is a lateral flow immunoassay for the detection of ochratoxin A in grain and feed.
Ochratoxin A antigen is coated on the test region of the nitrocellulose membrane of the strips, and ochratoxin A 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 ochratoxin A in the sample is over the detection limit, line T is blank; on the other wise, if ochratoxin A in the sample is less than the detection limit, line T is red.
Ochratoxins are a group of mycotoxins produced by some Aspergillus species and some Penicillium species . Ochratoxin A is the most prevalent and relevant fungal toxin of this group, while ochratoxins B and C are of lesser importance. Ochratoxin A is known to occur in commodities such as cereals, coffee, dried fruit, and red wine. It is possibly a human carcinogen and is of special interest as it can be accumulated in the meat of animals. Thus, meat and meat products can be contaminated with this toxin. Exposure to ochratoxins through diet can cause acute toxicity in mammalian kidneys.
