    Immunoaffinity Column for Aflatoxin B1

    The immunoaffinity column can selectively adsorb aflatoxin B1 from the sample solution, thereby purifying the sample. The purified sample solution can then be directly used for HPLC or LC-MS/MS analysis.

    Immunoaffinity columns can be used in combination with HPLC or LC-MS/MS to achieve rapid testing, and to increase signal-to-noise ratio and improve the accuracy of the detection method.

    Overview:

    Aflatoxins are toxic metabolites of a class of fungi (such as Aspergillus flavus and Aspergillus parasiticus). They are highly carcinogenic and are found mainly in grains, peanuts, nuts, cottonseeds, animal feed, vegetable oils, as well as animal tissues and blood. Among them, Aflatoxin B1 (AFT B1) ranks first in terms of toxicity, carcinogenicity and frequency of contamination.

    Principle:

    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. Aflatoxin is then eluted with methanol and injected into an analytical instrument for detection.
