Application

Aflatoxin G2 has been used as a standard to estimate the levels of aflatoxins by immunoaffinity column cleanup in:
  • peanut confection
  • Ginseng and other roots
  • olive oil, peanut oil, and sesame oil

Biochem/physiol Actions

Aflatoxins are hepatocarcinogenic and act as food contaminants in peanuts, fruits, cereals, corn, and dry fruits.

Disclaimer

Possibly carcinogenic.

General description

Aflatoxin G2 is a fungal secondary toxic metabolite synthesized by Aspergillus parasiticus, Aspergillus flavus, and Aspergillus nomius, species that are found in tropical and subtropical regions of the world. Aflatoxin Gs (AFGs) are derivatives of difuranocoumarin and contain a bifuran group linked to a coumarin nucleus and a lactone ring.

Journal of AOAC International, 89(3), 624-630 (2006-06-24)
Mycotoxins are toxic secondary metabolites produced by certain molds and are common contaminants of many important food crops, such as grains, nuts, and spices. Some mycotoxins are found in fruits, vegetables, and botanical roots. These contaminants have a broad range

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
