Mycotoxin (AFB1 / ZEN) Dual Fluorescence Quantitative Test Card Used For Cereal, Feed

                                        Mycotoxin (AFB1/ZEN) Dual Fluorescence Quantitative Test Card

                                                                                             CH60078

              The AFB1 /ZEN dual fluorescence quantitative test card applies the principle of competitive suppression immunochromatography. AFB1 , ZEN in the sample binds to the specific monoclonal antibody labeled with fluorescent microspheres during the flow process, and then inhibits the binding of the antibody to AFB1 , ZEN conjugations on the NC membrane detection line. The fluorescence signal is generated after excitation at a specific wavelength, and the intensity of the signal is inversely proportional to the AFB1 , ZEN contents in the sample.

Scope of Application

This product is suitable for the quantitative detection of AFB1 , DON in grain, feedstuff and some finished feed.

Procedures

   1. Preparation of instruments

(1) Turn on the portable fluorescence analyzer and preheat for 5 min.

(2) Turn on the incubator and heat to 37 °C. 2. Preparation of reagent (1) Please read the Instructions for Use carefully before the experiment, and recover the test reagents and the samples to room temperature (20-25°C) before use. (2) Insert the data card into the corresponding port of the analyzer.

(3) Tear the seal of the aluminum foil bag and remove the test card from the aluminum foil bag. Please use as soon as possible within 30 min. At most 8 samples can be tested at one time; if there are more than 8 samples, the samples can be tested in batches by 8 samples in one group.

(4) Transfer 150 µL of sample to be tested using a pipette with an appropriate range into the microsphere freezer-dried product, purge 2-3 times, immediately take 75 µL of the above solution into the injection well of the test card, and allow to react at 37°C for 7 min (pay attention to avoid obvious bubbles when pipetting and adding samples).
