1. Overview:

Deoxynivalenol, also known as vomitoxin, are monoposporin family of fungi, produced by some fusarium fungi. Vomitoxin are found mainly in wheat, barley, corn and other grains with the level of mg/kg, due to their high cytotoxicity and immunosuppression traits, they hold the threats to humans and animals’ health.

2. Principle:

The basis of the measurement is the antigen-antibody reaction. Antibodies are connected to the column and the sample is extracted, filtered, and diluted, and then passed slowly through the deoxynivalenol immunoaffinity column. The toxins bind to the antibodies in the column and the immunoaffinity column is then washed to remove other unrelated substances that have not been bound. Deoxynivalenol is eluted with methanol, and then dried with nitrogen and injected into the analytical instrument for detection.
