  • 产品描述:

    CUSABIO's Human SARS-CoV-2 nucleoprotein (N) IgG Antibody ELISA Kit allows for in vitro qualitative detection of the IgG antibody-specific for SARS-CoV-2 N protein in human serum and plasma. This research-use only kit can be applied in the studies associated with COVID-19, infectious and severe pneumonia caused by SARS-CoV-2. It has been validated with high sensitivity, high specificity, and high precision.

    Nucleoprotein is the most abundant protein in SARS-CoV-2. It packs the positive-sense single-stranded viral RNA into a helical ribonucleocapsid (RNP), forming the viral nucleocapsid (N). The N protein plays an important role in improving the efficiency of virus transcription and assembly. It is also involved in viral pathogenesis. N protein possessing an immunogenic effect makes it trigger an immune response, which leads to the production of IgM/G against SARA-CoV-2 N protein. SARS-CoV-2 N IgG antibodies appear in the serum after 2-3 weeks after the onset of the symptoms, peaks within the third week, and gradually declines to a lower level. IgG-specific for SARS-CoV-2 N protein rapidly increases to a higher level after a secondary infection and retains in the body for several months even years.

  • 本试剂盒所含材料:
      • A 96-well Coated assay plate --This microplate has been pre-coated with human SARS-CoV-2 nucleoprotein.
      • Negative Control (1 x 800 μl) --It is free of the SARS-CoV-2 N IgG antibody and used to preclude the false positive.
      • Positive Control (1 x 800 μl) --Used to evaluate the validity, stability, and comparability of the test results.
      • HRP-conjugated anti-Human IgG antibody (100 x concentrate) (1 x 120 μl) --Act as the detection antibody.
      • HRP-conjugate Diluent (1 x 20 ml) --Dilute the HRP-conjugated anti-Human IgG antibody.
      • Sample Diluent (2 x 20 ml) --Dilute the sample solution.
      • Wash Buffer (25 x concentrate) (1 x 20 ml) --Wash the unbound reagents.
      • TMB Substrate (1 x 10 ml) --React with HRP, eliciting a chromogenic color reaction.
      • Stop Solution (1 x 10 ml) --Stop the color reaction. The solution turns from blue to yellow.
      • Four Adhesive Strips (For 96 wells) --Seal the microplate when incubation.
