Charm manufactures a variety of ROSA (Rapid One Step Assay) tests to detect mycotoxins (aflatoxin, DON/vomitoxin, fumonisin, ochratoxin, T2/HT2, and zearalenone) in feed and grain. Utilizing innovative ROSA technology, Charm lateral flow mycotoxin tests are easy to use and provide rapid, quantitative results. All ROSA mycotoxin tests follow a similar assay format and can be read on the same equipment.
Test results from ROSA strips may be read and officially recorded using the Charm EZ-M system, or the ROSA-M Reader.
Charm II tests run on the Charm II system and are designed for use by veterinarians, laboratory and regulatory personnel. They provide a comprehensive analysis of biological residues on multiple matrices, and meet EU MRLs and US FDA Safe Levels.
Charm II tests use a binding reagent with specific receptor sites. The binder is added to a sample along with an exempt amount of labeled tracer. Any 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 drug concentration in the sample. The smaller the amount of tracer measured, the greater the drug concentration in the sample.
