The aflatoxin group of mycotoxins consists of about 20 secondary metabolites of Aspergillus flavus, Aspergillus parasiticus and Aspergillus nominus. These fungi predominantly grow in hot climates and infect different foods such as cereals, nuts, spices and dried fruit. Aflatoxin B1 the main concern as it is a potent carcinogen. However, aflatoxin B2, G1, G2, M1 and M2 are all acutely and chronically toxic. Cattle metabolise aflatoxins B1 and B2 to aflatoxins M1 and M2 and therefore residues of the latter are a health hazard for consumers of milk.

The side-effects in humans from consuming aflatoxin residues include liver cancer, chronic hepatitis and cirrhosis. EU regulations specify the limits for the total content of aflatoxins B1, B2, G1 and G2 as 4-15 ppb in various foods.

Total Aflatoxins Rapid kit has been developed for the rapid and reliable quantification of aflatoxins in grain, including wheat, barley and corn/maize, as well as in pistachios, peanuts, almonds, dried fruits, rice and cornflakes.

Technical features:

· Quantitative method
· Competitive indirect-type ELISA
· Ready-to-use reagents
· Rapid assay, including 20 min. total incubation time
· Simplified interpretation of results
· Detects aflatoxin B1, B2, G1 and G2
· Limit of detection: 1.8 ppb

2) Aflatoxin B1

Aflatoxin B1 Rapid Assay

Description:

Aflatoxins are metabolites of the mould fungi Aspergillus flavus and Aspergillus parasiticus. In foodstuffs Aflatoxin B1 is most common. Given the very high toxicity of the aflatoxins, especially B1, many countries have defined a maximum permitted level of mycotoxins, with levels from 0 to 50 ppb of Aflatoxin B1 depending on the test matrices.

Aflatoxin B1 rapid kit is intended for the qualitative screening of aflatoxin B1 in food and feedstuffs.

Technical features:
· Detection limit 0.5ppb. in compliance
with most common national regulations
· Suitable for large test series
· Quantitative or qualitative detection
· Ready-to-use reagents
