  1. General Aflatoxins are secondary metabolites of the fungi species Aspergillus flavus, parasiticus and nomius. Aflatoxins belong to the strongest natural occurring carcinogenic substances, commonly found in corn, peanuts, cotton seed, human blood and animal feed.Aflatoxin B1 appears nearly in all cases together with Aflatoxin B2, G1 and G2 and it is the analyte with the highest toxic significance.Thin-layer chromatography has been a common method of aflatoxin detection, but sample preparation and samples analysis of this method is time-consuming and exhausting. The use of aflatoxin B1 ELISA kit to analyze aflatoxin B1 residue of samples is fast and accurate. Refer to the National Standard GB / T 5009.22-2003. This kit is a new generation of fungal toxins detection products in application of ELISA technology and the operation time is shorter than 60min, to minimize operating errors and work intensity. 2. Principle The test is based on a direct competitive enzyme immunoassay method. The microtiter wells are coated with aflatoxin antigen. Free aflatoxin in sample solutions and the immobilized antigen compete for aflatoxin enzyme conjugate. Any unbound enzyme conjugate is then removed in a washing step. Substrate/chromogen is added to the wells, bound enzyme conjugate converts the chromogen into a blue product. The addition of the stop solution leads to a color change from blue to yellow. The measurement is made photometrically at 450 nm. The absorbance is inversely proportional to the aflatoxin concentration in the sample. 3. Application This test kit can be used to detect aflatoxin B1 in maize, rice, wheat, beans, peanuts, peanut butter, feed, edible oil and other samples qualitatively and quantitatively. 4. Technical specifications Sensitivity: 0.1 ppb Detection limit: Peanuts, peanut butter, cereals, pastries …………………………………………2ppb Feed
