DON belongs to the single-endomycin family of molds and is produced by certain Fusarium fungi. 3-ADON and 15-ADON are derivatives of DON. These toxins are mostly distributed in grain seeds such as wheat, barley, and corn. Due to their high cytotoxicity and immunosuppressive properties, they pose a health threat to humans and animals.
Product Properties: DON 2000ng, 3-ADON 1000ng, 15-ADON 2000ng;
Samples: Grain, oil, feed, alcohol, condiments, etc.
The basis of the measurement is the antigen-antibody reaction. Antibodies are connected to the column and the aflatoxin in the sample is extracted, filtered, and diluted, and then passed slowly through the aflatoxin 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 then eluted with methanol and injected into an analytical instrument for detection.

Allow the immunoaffinity column to return to room temperature (22 to 25°C) before use.
The affinity column should be stored at 2 to 8°C, do not freeze.
Dot use any expired immunoaffinity column.
The sample volume can be increased or decreased appropriately as required, and the volume of the extraction solution should be adjusted accordingly.

6.1 The pH of the loading solution of the affinity column should be within the range of 6 to 8. If it deviates from this range, the pH should be adjusted with dilute hydrochloric acid or dilute sodium hydroxide.
6.2 Maintaining consistency (such as polarity, pH, and concentration) between the test solvent loaded into any analytical instrument and the mobile phase can help eliminate any adverse solvent effects.
6.3 WARNING: Aflatoxin is toxic and carcinogenic; protective equipment such as gloves and masks should always be used during handling.
