Description:
- COVID-19 nucleocapsid recombinant antigen (NP) is bound to the well surface of the microtiter plate.
- If specific antibodies are present, they bind to the antigen, are labeled by the Conjugate in the following steps and are detected by color reaction with a single component substrate (TMB-Complete).
- The kit allows 96 tests, including controls in a split microtiter plate with color-coded strips and breakable wells.
Advantages:
- The total assay time is about 1 hour 30 min.
- High sensitivity and specificity of the test.
- Kit includes CUT-OFF, Positive Control, Negative Control and Calibrators (5, 20, 80, 320 U/ml).
- Semi-quantitative evaluation in the Index of Positivity (IP) or quantitative evaluation in U/ml.
- Ready-to-use, color-coded components.
- Single-component substrate.
- Interchangeable components with the exception of kit specific components (Controls, Conjugate, Plate).
Application:
- Identification of patients with asymptomatic infection in the past.
- Differentiation between naturally acquired and vaccination antibodies.
- Prevalence studies.
