For use in the grain industry, the new ROSA® (Rapid One Step Assay) follows the same format that other Charm Mycotoxin tests use, as follows:
Add the sample extract to the ROSA T2-HT2 test trip, incubate and count in the ROSA-M reader. Results are available in two ranges: 0-250 ppb, and 0 -2.5 ppm.

The Charm ROSA T2-HT2 provides a long-sought tool to rapidly and accurately detect T-2 and HT-2 toxins that adversely affect animal and human health. T-2 and HT-2 are trichothecene toxins generated by several Fusarium species (e.g., F. sporothrichioldes) in corn, wheat, barley, rye and oats. These toxins are known to cause feed refusal, edema, vomiting, immunosupression and gastrointestinal inflammation in animals, and alimentary toxic aleukia in humans.

In addition to the Charm ROSA T2-HT2 test, the following ROSA mycotoxin tests are available.
