Aflatoxin Total ELISA Kit

Full Name: Aflatoxin Total ELISA Kit
Sample Type: Food (Chillies, Cereals, Oils, Dry Fruit, Beer, Nuts)
Sensitivity: 0.05 ng/ml

BACKGROUND

Aflatoxin is a family of toxins present naturally in a number of foods and in some cases be associated with cancer if eaten in large quantities. Some of the foods which include this are frequently found in improperly stored staple commodities such as: variety of species, cassava, cotton seed, peanuts, corn (maize), chilli peppers, millet, wheat, tree nuts, rice, sunflower seeds, sesame seeds and sorghum. The following assay procedure offers a highly sensitive detection system which can be used for samples such as nuts, cereals, chillies, dry fruit, oils and beer.

Aflatoxin is mostly ingested, but some (specifically B1), can permeate through the skin. Detection methods include analysing AFB1-guanine adducts (in urine) or AFB1-albumin adducts (in blood serum) which can be done with ELISA immunoassays. Trichothecenes are a large group of mycotoxins produced by various species of fungi. They are classified as being a class of polyether toxin, meaning they contain multiple ether groups in their structure. The most well-known trichothecene is T-2 toxin which is produced by “Fusarium verticillioides”.

INTENDED USE

Aflatoxin total ELISA kit is intended for detecting quantitative concentrations of total aflatoxin in food (such as cereals, dry fruit, nuts, chillies, beer and oils). This assay has a minimum analytical sensitivity limit of 0.05 ng/ml.
