New test for T-2 and HT-2 mycotoxins

Charm Sciences, Inc. has released the first lateral flow quantitative test for T-2 and HT-2 toxins.

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. 

In addition to the ROSA T2-HT2 test, the following ROSA mycotoxin tests are available:
- 3 minute quantitative test for aflatoxin in corn
- 3 minute qualitative test for DON in wheat and barley
- 10 minute quantitative tests for aflatoxin, DON, fumonisin, ochratoxin and zearalenone in multiple commodities.
