Rapid Strip Test for Beta-lactam and Tetracycline Antibotic Residues in Milk

The AuroFlow^™ PR1ME^™ BT Combo MRL Assay is a qualitative and rapid lateral flow assay designed for the detection of a broad range of antibiotics in raw, commingled cow's milk. These rapid tests detect 17 beta-lactams plus metabolites and 3 tetracyclines below EU MRL requirements in a one-step process. The fast, simplified protocol can be seen in the next tab. Results of the test can be interpreted visually. If any test line on the strip is less intense than the control line, the sample is positive for that antibiotic.

Beta-lactam antibiotics are a class of broad-spectrum antibiotics, consisting of all antibiotic agents that contain a beta-lactam ring in their molecular structures. This includes penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems. Most beta-lactam antibiotics work by inhibiting cell wall biosynthesis in the bacterial organism, and they are the most widely used group of antibiotics. Tetracycline is also a broad spectrum antibiotic frequently employed in dairy cow production.

This kit is manufactured to the international quality standard ISO 9001.
