Just add milk

BetaStar® Advanced for Beta-lactams is a rapid detection test for penicillin, ampicillin, amoxicillin, cloxacillin, cephapirin and ceftiofur in raw, commingled cow milk, offering results in just five minutes. It holds approvals from the AOAC-RI and the National Conference on Interstate Milk Shipments. BetaStar Advanced is designed to work exclusively with NEOGEN’s state-of-the-art Raptor Integrated Analysis Platform, which controls the volume, temperature and runtime of up to three test strips at once — allowing you to simply add milk and walk away.

1 The tolerance level for each of the tetracycline antibiotics has been set by the FDA as the sum of all tetracyclines.

2 The 90/95 sensitivity level was calculated from data collected during validation testing by a third party laboratory. Sensitivity was based on testing multiple levels of each beta-lactam antibiotic samples per concentration.


The milk is wicked through a reagent zone, which contains antibodies and receptors conjugated to colloidal gold particles. If beta-lactams or ceftiofur are present, they will be captured by their particle-antibody complex. The drug-antibody-particle complex then is wicked onto a membrane. The membrane contains two separate and independent test lines, with one consisting of a drug conjugated to a protein carrier designed to capture the beta-lactams and the other test line consisting of a drug-protein conjugate designed to capture ceftiofur. These independent test lines capture any antibody / receptor gold particle complexes (in absence of antibiotics) to concentrate and form a visible line. As the level of a particular drug in the sample increases, free drug molecules will complex with the antibody/receptor gold particles. This allows less antibody-gold to be captured into the test lines. 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.
