CD Cephapirin Rapid Test is a competitive immunoassay for the semi-quantitative detection of the presence of Cephapirin residue in milk.
Cefapirin (INN, also spelled cephapirin) is an injectable, first-generation cephalosporin antibiotic. It is marketed under the trade name Cefadyl. Production for use in humans has been discontinued in the United States. It also has a role in veterinary medicine as Metricure, an intrauterine preparation and combined with prednisolone in Mastiplan, an intramammary preparation. Both are licenced in cattle.
Principle Of The Test
CD Cephapirin Rapid Test is based on competitive lateral flow immunochromatographic assay. The Cephapirin conjugate in the test zone will capture the immuno-gold (colloid gold- Cephapirin antibody conjugate), when there is very little dissociative Cephapirin in the samples. A visible red test band indicates a negative result when the control line (C zone) shows that the card is valid. The test band (T zone) will be not visible if Cephapirin is present in concentration of 10 ppb and above which explains a positive result.
