The CDIATM Pb Colloidal Gold Test Cassette (Milk) is a lateral flow immunoassay for the detection of Pb in Milk.
Pb antigen is coated on the test region of the nitrocellulose membrane of the strips, and Pb 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 Pb in the sample is over the detection limit, line T is blank; on the other wise, if Pb in the sample is less than the detection limit, line T is red.
Lead is a chemical element with symbol Pb (from the Latin plumbum). It is a heavy metal with a density exceeding that of most common materials. In the late 19th century, lead was recognized as highly toxic, and since then it has been phased out for many applications. Lead is a neurotoxin that accumulates in soft tissues and bones, damaging the nervous system and causing brain disorders and, in mammals, blood disorders. The CDIATM Pb Colloidal Gold Test Cassette (Milk) is a lateral flow immunoassay for the detection of Pb in Milk.
