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.
