Charm II Beta-lactam Test for Feed and Grain
>> Available in kits of 100 and 500 tests

charm ii_newlogo Charm provides a Charm II test to detect beta-lactam antibiotics in feed and grain. Common members of the beta-lactam family of antibiotics include: penicillin, cephapirin, ceftiofur, ampicillin, amoxicillin, cloxacillin, oxacillin, dicloxacillin, cefquinome, nafcillin, cefazolin, cefodroxil, cefotaxime, cephalexin, cephradine, hetacillin, penethamate, piperacillin, and ticarcillin.

How It Works
Charm II Beta-lactam Tests use a binding reagent with specific receptor sites that bind beta-lactam drugs. The binder is added to a sample along with an exempt amount of labeled penicillin (tracer).Any beta-lactam drugs in the sample compete for the binding sites with this tracer. The amount of tracer that binds to the receptor sites is measured and compared to a previously determined Control Point. The Control Point is the cutoff point between a negative or positive sample. The greater the amount of tracer measured, the lower the beta-lactam concentration in the sample. The smaller the amount of tracer measured, the greater the beta-lactam concentration in the sample.
