The CDIATM Vitamin B12 Colloidal Gold Test Cassette (Milk) is a lateral flow immunoassay for the detection of Vitamin B12 in milk.
Vitamin B12 antigen is coated on the test region of the nitrocellulose membrane of the strips, and Vitamin B12 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 Vitamin B12 in the sample is over the detection limit, line T is blank; on the other wise, if Vitamin B12 in the sample is less than the detection limit, line T is red.
Vitamin B12 is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system via the synthesis of Myelin, and the formation of red blood cells. It is one of eight B vitamins. It is involved in the metabolism of every cell of the human body, especially affecting DNA synthesis, fatty acid and amino acid metabolism. B12 is the largest and most structurally complicated vitamin. The CDIATM Vitamin B12 Colloidal Gold Test Cassette (Milk) is a lateral flow immunoassay for the detection of Vitamin B12 in milk.
