Deoxynivalenol (DON) immunochromatographic test for fast detection of deoxynivalenol mycotoxin in cereal, feed and nut.
Deoxynivalenol belongs to trichothecenes of group B and is produced by the Fusarium in convenient temperature 21-25°C. That mycotoxin characterizes with resistance to high temperature (170-350°C). Deoxynivalenol is a chromatographic immunoassay kit for rapid detection of DON. The method is based on immunocompetence ELISA test. The binding of the test substance to the receptor surface binding site is examined to detect the mycotoxin in sample. Different color changes indicate different concentrations. This technology has high specificity, sensitivity, strong stability and anti-interference ability. The more mycotoxins in the sample, the less fluorescent-labeled antibodies is binding to the test line. The detection limit is 500 ppb.

SPECIMEN COLLECTION AND STORAGE
INTERPRETATION OF THE RESULTS:
POSITIVE: T line color is the same as C line, T line color is weaker than C line or C line is colored and T line is not colored at all. That means, that the concentration of deoxynivalenol in the sample is equal to or higher, than the detection limit.
NEGATIVE: Both, the C and T lines are colored and the T line is stronger than the C line. That indicates, that the concentration of deoxynivalenol in the sample is below the detection limit.
INVALID: The C line does not appear, indicating the incorrect operation process or strip deterioration. In this case, read the instructions carefully and retest with a new strip. If the test strip needs to be recorded, please cut off the lower sponge pad immediately after the interpretation and dry it for archiving.
