BetaStar® S for Quinolones is an assay for the rapid detection of quinolone antibiotics in raw, commingled milk and other dairy products at or below established Maximum Residue Levels (MRL). BetaStar S for Quinolones is designed to work with the Raptor® Integrated Analysis Platforms. The test can also be read visually.

The milk is wicked through a reagent zone, which contains antibodies conjugated to colloidal gold particles. If quinolones are present, they will be captured by the particle-antibody complex. The drug-antibody-particle complex then is wicked onto a membrane, which contains a sulfonamide drug conjugated to a protein carrier. This line captures any uncomplexed drug antibody, allowing the particles to concentrate and form a visible line. As the level of quinolones in the sample increases, free drug molecules will complex with the antibody-gold particles. This allows less antibody-gold to be captured in the test line. Therefore, as the concentration of a drug in the sample increases, the test line density decreases. The membrane also contains a control line where an immune complex present in the reagent zone is captured by an antibody, forming a visible line. The control line will always form regardless of the presence of the drug, ensuring the strip is functioning properly.
