General description

Aflatoxin B1 is the most toxic aflatoxin. Aflatoxins are hepatotoxic metabolites, that are produced by molds, such as Aspergillus flavus and Aspergillus parasiticus. Aflatoxins contaminate human food and animal feed. They are linked to liver cancer, immune system suppression, reduced growth rates, losses in feed efficiency and death. They are naturally found toxic carcinogens and the most widely known mycotoxins. They mainly contaminate fruits, vegetables and grains.

Application

Aflatoxin B1 is a carcinogenic compound that induces transversion of G to T at codon 249 of the p53 tumor suppressor gene.
Aflatoxin B1-BSA Conjugate from Aspergillus flavus has been used in immunization of mice with phage and synthetic peptide. It is also used as a target molecule in si field-effect transistor (FET) biosensing techniques.

Disclaimer

Possibly carcinogenic.

Rabbit (outbred albino New Zealand White) antisera have been raised against aflatoxin B1 (AFB1) using as immunogen conjugates in which the hapten was coupled to bovine serum albumin (BSA) either through C1 or C8 with the oxime and the dichloride

We reported previously on the properties of an anti-aflatoxin B1 (AFB) antiserum raised with a conjugate in which AFB is coupled at the C8 position to bovine serum albumin (BSA). The hapten/carrier protein molar ratio of the conjugate was 14.
