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.

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.

Warning

Possibly carcinogenic.

Aflatoxins produced by the Aspergillus species are highly toxic, carcinogenic, and cause severe contamination to food sources, leading to serious health consequences. Contaminations by aflatoxins have been reported in food and feed, such as groundnuts, millet, sesame seeds, maize, wheat

An easy method for the determination of aflatoxins B1, G1, B2 and G2 in Rhammus purshiana by LC coupled to mass spectrometry has been developed. Aflatoxins were extracted with a mixture of methanol and water and then it was purified

The aim of this study was to investigate the feasibility of using multitime-regenerated immunoaffinity column (IAC) for aflatoxins B1, B2, G1 and G2 in peanut confection. After each use, the IAC was washed immediately with phosphate-buffered saline and stored for >12h

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.
