SARS-CoV-2 Neutralizing Antibody Rapid Test Kit With CE Certificate And Instrument
A neutralizing antibody (NAb) is an antibody that is responsible for defending cells from pathogens, which are organisms that cause disease. They are produced naturally by the body as part of its immune response, and their production is triggered by both infections and vaccinations against infections.
|RFU Results||Result||Dilution Titer||Test Result Interpretation|
|<20%||Negative||<1:20||Neutralizing antibodies for 2019-nCoV are not detected at 50% virus neutralization|
|20%-50%||Positive (Low titer)||1:20~1:160||Low neutralizing antibodies for 2019-nCoV are detected at 50% virus neutralization.|
|>50%||Positive (High titer)||>1:160||High neutralizing antibodies for 2019-nCoV are detected at 50% virus neutralization.
Based on the principle of Immunofluorescence analysis, SARS-CoV-2 Neutralizing Antibody Assay Kit by Immunofluorescence Chromatography Method was used to immobilized ACE-2 protein (T line) and goat anti-chicken IgY Antibody (C line) using nitrocellulose membrane (NC) as solid phase carrier. Fluorescent microspheres were conjugated to recombinant SARS-CoV-2 S-RBD antigen in the fluorescent labeling pad.
When the buffer solution was added to the sample well, the S-RBD-labeled fluorescent microspheres in the labeling pad were pushed to bind to the corresponding immobilized ACE-2 protein on the NC membrane, and the fluorescent signal could be detected at the marking position. If there is a neutralizing antibody in the sample, it will bind to the labeled S-RBD antigen when passing through the labeling pad. The neutralizing antibody can prevent the binding of S-RBD to ACE-2, resulting in a decrease in the signal value, and he T-line signal value is negatively correlated with the neutralizing antibody content.
