Description:

Beta Star is a receptor assay test for rapid determination of B-lactam and cephatosporin antibiotics (e.g. penicillin, ampicillin, cephalonium etc.) in milk. The test is based on a specific B-lactam receptor and a protein, linked to gold particles.

There are 2 steps to the test. During the preliminary incubation, milk is added to a known amount of receptor which will react with any B-lactams present.

In the second stage, the incubated medium is allowed to migrate up a stick of chromatography paper containing a biomolecule band recognizing the receptor, lf the receptor has not been in contact with B-lactams, the biomolecule band will capture all the receptor molecules, which results in a visible red band being formed and the test is negative. lf no red band is formed, the receptors have been blocked by the B-lactams and the test is positive.
