Aspergillus flavus immunoaffinity column

The basis for the determination of this product is antigen antibody reaction. Aspergillus flavus antibody is fixed on the gel in the column. The Aspergillus flavus in the sample is extracted, filtered, diluted, and then slowly passes through the Aspergillus flavus immune affinity column

　　Aspergillus flavus immunoaffinity columnProduct Overview:

Aflatoxin is a secondary metabolite produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. It is classified as a Class 1 carcinogen by the World Health Organization's Agency for Research on Cancer and is also a highly toxic substance. Widely present in various foods, such as corn, peanuts, rice, wheat and other grains and their by-products. The Aspergillus flavus M1 produced by animal metabolism of Aspergillus flavus B1 in feed still has strong toxicity and carcinogenicity, and is widely present in foods such as milk, blood, and tissues. Aspergillus flavus, as one of the three major causes of liver cancer and the main cause of diseases such as gastric cancer and colon cancer, poses a great threat to human health. Countries around the world have strict regulations on the use of Aspergillus flavus in food and feed.

Reaction principle:

The basis for the determination of this product is antigen antibody reaction. Aflatus antibody is fixed on the gel in the column. Aflatus in the sample is extracted, filtered, diluted, and then slowly passed throughAspergillus flavus immunoaffinity columnIn the column, Aspergillus flavus specifically binds to antibodies, and then the immunoaffinity column is washed to remove any unbound substances. Wash Aspergillus flavus with methanol and inject it into the analytical instrument for detection.

Product packaging composition:

Each box contains 25 Aspergillus flavus total immunoaffinity columns and 1 set of corresponding instructions.

Notes:

1. Aspergillus flavus is harmful to the human body and should be operated with gloves.

2. Soak the used glass container and Aspergillus flavus solution in a 5% concentration sodium hypochlorite solution overnight.

3. Do not use immunoaffinity columns that have exceeded their expiration date.

4. When not in use, the immunoaffinity column should be stored at 2-8 ℃ and cannot be frozen.

5. Before use, the immunoaffinity column needs to be returned to room temperature (22-25 ℃).

6. Sampling volume: It can be adjusted appropriately according to the actual situation, but not too little. At the same time, the volume of the extraction solution should be proportionally changed accordingly.

7. PH: The pH of the upper column solution should be between 6 and 8. If it deviates from this range, hydrochloric acid or * should be used to adjust the pH.
