AFB₁ fluorescence quantitative detection reagent applies the principle of competitive suppression immunochromatography. AFB₁ 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- BSA conjugate 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 content in the sample.

Scope of Application

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