Veratox for T-2/HT-2 is a competitive direct ELISA in a microwell format that allows the user to obtain exact concentrations in parts per billion (ppb) of either T-2, HT-2 or a combination of both. Free T-2 or HT-2 toxins in the samples and controls are allowed to compete with enzyme-labeled HT-2 toxin (conjugate) for the antibody binding sites. After a wash step substrate is added, which reacts with the bound conjugate to produce blue color. More blue color means less T-2/HT-2 toxins. The test is read in a microwell reader to yield optical densities. The optical densities of the controls form the standard curve, and the sample optical densities are plotted against the curve to calculate the exact concentration of T-2/HT-2 toxins.
