A test portion is blended with methanol–3% aqueous sodium bicarbonate solution (50 + 50). The extract is filtered, diluted with phosphate-buffered saline (PBS), and applied to an immunoaffinity column containing antibodies specific for OTA. After washing, the toxin is eluted from the column with methanol and quantified by liquid chromatography (LC) with fluorescence detection.
