Full Name: Aflatoxin B1 ELISA Kit
Sample Type: Cereals, Beer/Gyle
Sensitivity: 0.5 ppb
Aflatoxin B1 is an incredibly potent carcinogen that is produced by Aspergillus flavus and A. parasiticus. However, this carcinogenic potency tends to vary across many different species for example rats displays a higher susceptibility when compared to monkeys. It can induce lung, colon and kidney carcinoma in dogs, rats, rodents and fish. The susceptibility is known to be age, sex and species dependent. Aflatoxin B1 induced mutations in the G-2448AGT polymorphism of the p53 gene, associated with increased risk of bladder cancer, are seen in human population populations exposed to high amounts through consumption of contaminated food stuffs such as maize, peanuts and rice. The primary route of exposure for humans is consumption of contaminated food stuffs such as maize, peanuts, rice, milk and eggs; while the route of exposure for birds is via feed contaminated with the fungal toxin.
Aflatoxin B1 is found in contaminated food such as; corn, cottonseed meal, peanuts and many other grains. Some of the common analytical procedure which have been used include HPLC, TLC, mass spectrometry and ELISA assays.
Aflatoxin B1 ELISA kit is a method for rapid quantitative measurement of aflatoxin B1 in beer/gyle and cereals. This assay has a minimum analytical sensitivity limit of 0.5 ppb.
All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
