Test principle
This assay is based on the competitive enzyme immunoassay for the detection of AFM1 in the sample. The coupling antigens are pre-coated on the micro-well stripes. The AFM1 in the sample and the coupling antigens pre-coated on the micro-well stripes compete for the anti-AFM1 antibodies. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density (OD) value of the sample has a negative correlation with the AFM1 in it. This value is compared to the standard curve and the AFM1 concentration is subsequently obtained.
Product Overview
Aflatoxins are naturally occurring mycotoxins that are produced by Aspergillus flavus and Aspergillus parasiticus, species of fungi. The name, aflatoxin, was created around 1960 after the discovery that the source of "Turkey 'X' disease" was Aspergillus flavus toxins. Aflatoxins are toxic and among the most carcinogenic substances known. After entering the body, aflatoxins may be metabolized by the liver to a reactive epoxide intermediate or hydroxylated to become the less harmful aflatoxin M1. At least 14 different types of aflatoxin are produced in nature. Aflatoxin B1 is considered the most toxic and is produced by both Aspergillus flavus and Aspergillus parasiticus. Aflatoxin G1 and G2 are produced exclusively by A. parasiticus. While the presence of Aspergillus in food products does not always indicate that harmful levels of aflatoxin also are present, it does imply a significant risk in consumption. Aflatoxins M1, M2 originally were discovered in the milk of cows that fed on moldy grain. These compounds are products of a conversion process in the animal's liver, however, aflatoxin M1 is present in the fermentation broth of Aspergillus parasiticus.
Precision
Intra-assay Precision (Precision within an assay)
Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays)
Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
CV (%) = SD/meanX100
Intra-Assay: CV<8%
Inter-Assay: CV<12%
Stability
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37C for 4 and 7 days, and compare O.D.values of the kit kept at 37C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37C can be considered as 6 months at 2 - 8C, which means 7 days at 37C equaling 12 months at 2 - 8C).
Storage
Store at 2-8C. Please refer to Instruction Manual.
