The CDIATM Olaquindox Metabolite Colloidal Gold Test Cassette (Meat) is a lateral flow immunoassay for the detection of olaquindox metabolite in meat.
MQCA antigen is coated on the test region of the nitrocellulose membrane of the strips, and MQCA 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 MQCA in the sample is over the detection limit, line T is blank; on the other wise, if MQCA in the sample is less than the detection limit, line T is red.
Olaquindox (OLA) is related to quinoxaline-N-dioxide, which is an antimicrobial drug that is used as a growth promoter to improve the feed conversion efficiency and to increase the rate of weight gain in livestock farming. But it may lead to carcinogenic, mutagenic, and photoallergenic effects. 3-methyl-quinoxaline-2-carboxylic acid (MQCA) is the last major remaining detectable metabolite of OLA in animals and is the marker substance for OLA that was designated by the WHO/FAO Joint Expert Committee on Feed Additives (JECFA) in 1995. The CDIATM Olaquindox Metabolite Colloidal Gold Test Cassette (Meat) is a lateral flow immunoassay for the detection of olaquindox metabolite in meat.
