    3. Specifications: 8 dipsticks/bottle, 12 bottles/box


    4. Principle

    The Total Aflatoxins rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. In the flow process, Total Aflatoxins in the sample combined with Total Aflatoxins specific colloidal gold-labeled monoclonal antibody, Inhibit the combination between antibody and TAF -BSA conjugate on Test line of NC membrane, lead to the color change of Test line.

    When the sample has no Total Aflatoxins residue or concentration lower than detection limit, T line is darker than or has same color with C line. when the concentration is equal to or higher than detection limit, T line is lighter than C line obviously or T line is invisible. No matter whether there is Total Aflatoxins residue in sample, C line will appear, it means the test is valid.

    7. Operation procedures

    7.1 Read the instruction carefully before use. Return test dipsticks and sample into room temperature.

    7.2 Take bottles needed from the kit package, take out required micro-wells and dipsticks, making proper marks. Please use these test dipsticks within 1h. Seal the cap of the bottles, avoid moisture.

    7.3 Take 200ul of the test samples into the micro-wells, then repeatedly absorb for 5 times, mix the sample with the reagent in the micro-wells completely until no solid judge by eyes (this is a very important step).

    7.4 Incubate for 3min at room temperature(20-25℃), then insert the test dipsticks into the micro-wells with the "MAX" end fully dipped in to the mixture solution.

    7.5 Insert the test dipsticks into micro-wells for 5-8min then read the result, it is invalid in other time.


    8. Test Result Interpretation

    8.1 Negative: T line is darker than or has same color with C line. It means there is no Total Aflatoxins residue in sample or the residue is lower than detection limit.

    8.2 Positive: T line is obviouly lighter than T lin or T line is invisible. It means the Total Aflatoxins residue is higher than or equal to detection limit.

    8.3 Invalidation: C line isn’t seen wine red. It means the test strip is out of efficacy, out of date or improper operation. Please run the test again using another package. If the invalid tests keep happening, please contact the local distributor.
