POCT detection-fluorescent microsphere ±$≤labeling technology

Fluorescent microsphere labeling technδβ™®ology uses the princ↕₩÷iple of membrane chromatography d®  εouble antibody sandwich method to<★ detect influenza A and / or §™influenza B virus antigens in samples. Du ✘ring the test, the treated samples are add​↔​ed dropwise to the sample wells corresponding γ✘↕to the two detection areas of the test cards A ↕≈&"and B. When the influe≠ 'δnza A and (or) B viruses are present in the sa←‍mple, the virus antigen and qua←← Ωntum dot nanospheres After the labeled influ☆♥ enza A and (or) influenza B virus nucleopro γ≈tein monoclonal antibody I is combined, when t¶  φhe chromatography line is >®detected, it will be captured by the coateπ&d influenza A and (or) influenza B v'♦≤αirus nucleoprotein monoc±>lonal antibody II Gather at the position of the d∑<etection line to form a fluorescent band A li• ne and (or) B line. Under ultravi✔™™olet irradiation with a wavelen≥∏gth of 365nm, it can be determined §©σby the naked eye that the influenza A an± β←d (or) B virus is positive, or by fluores£←cence The result of the chrom >atography test strip reader β is positive for influenza A and / or B viruses∞ §.
