ROSA AFQ-WETS5 Aflatoxin Quantitative Test

SKU:N/A Category:


The ROSA AFQ-WETS5 Aflatoxin Quantitative Test detects aflatoxin rapidly and quantitatively utilizing ROSA (Rapid One Step Assay) lateral flow technology. The WET method uses an extraction powder added to the sample followed by water (e.g., bottled water) to extract aflatoxin.


In 2015, the U.S. Department of Agriculture (USDA), Grain Inspection, Packers and Stockyards Administration (GIPSA) has awarded a 5-year contract to Charm Sciences to monitor aflatoxin in grains utilizing Charm’s ROSA WET-S5 Aflatoxin Quantitative Test (water-based) and ROSA FAST Aflatoxin Quantitative Test (solvent-based). This Rapid One Step Assay is a quantitative lateral flow test that is read in the Charm EZ-M system or the ROSA-M Reader.

The ROSA AFQ-WET-S5 test is USDA GIPSA (Grain Inspection, Packers & Stockyards Administration) approved for detecting aflatoxin in the following commodities:

Quantitative results in 5 minutes
GIPSA validated for Corn, DDGS, Sorghum, Soybeans, Wheat
Materials may be disposed as normal waste providing positive mycotoxin samples do not violate local regulations
Water extraction – no methanol or ethanol required
Uses existing equipment; ROSA-M Reader and Charm EZ-M system do not require end-user instrument calibration, standard curve built into reader
