Rapid Strip Test for Beta-lactam Antibotic Residues in Milk

The AuroFlow PR1ME Beta-Lactam 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. The PR1ME rapid tests detect 14 beta-lactam antibiotics in milk at or below EU and CODEX Maximum Residue Limits (MRL) in an ILVO-validated one-step process. The fast, simplified protocol can be seen in the next tab. Results of the test can be interpreted visually. Beta-lactam line signal intensity that is equal to or stronger than the signal at the C-line indicates a negative result. Signal at the Beta-lactam line which is less intense compared to the C-line indicates a positive result.

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.

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

Rapid Test Kits to Detect Residues in Dairy Products

Strip tests detect the most commonly used antibiotics found in cow’s milk. These AuroFlow tests are fast and easy-to-use in a laboratory or in the field, without requiring any additional equipment. In fact, milk can be directly introduced to a sample tube in the new AuroFlow PR1ME kits – the mixing step having been eliminated – and the test strip inserted immediately for results within minutes. PerkinElmer’s test strips are manufactured to test for European Union and CODEX maximum residue limits (MRL). PerkinElmer offers solutions for the detection of a multitude of drug residues, pasteurization verification, and Aflatoxin M1 by other methods such as ELISA based testing.
