Technology

DON is extracted from a ground sample by blending and filtering. Extracted toxin in the filtrate is sampled and diluted with water. The diluted extract is filtered and applied to the column. Positive pressure is used to induce flow through the column allowing the antibody to capture any DON present. Then, the column is washed to remove any unbound materials. Bound DON is eluted using 100% methanol and is detected by HPLC or Veratox® enzyme-linked immunosorbent assay (ELISA) methods.
