ROSA AFQ-WETS5 Aflatoxin Quantitative Test

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 (organic solvent-based). See the announcement in the News tab below.
