This ELISA kit uses Indirect-ELISA as the method to qualitatively detect the SARS-CoV-2 Nucleocapsid protein IgG in the sample. The micro ELISA plate provided in this kit is pre-coated with purified SARS-CoV-2 Nucleocapsid protein (E-ELC-001) antigen, after adding samples to wells, the SARS-CoV-2 Nucleocapsid protein IgG in the samples will combine with the pre-coated SARS-CoV-2 Nucleocapsid protein antigen. After washing completely, add Horseradish Peroxidase (HRP) conjugated mouse anti human IgG to develop the antigen-antibody-HRP conjugated secondary antibody complex. Free components are washed away, then the substrate solution is added to each well. Only those wells that contain SARS-CoV-2 Nucleocapsid protein IgG and HRP conjugated anti-human IgG will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ± 2 nm. Compared with the CUT OFF value to judge whether SARS-CoV-2 Nucleocapsid protein IgG exists in the tested samples or not.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to SARS-CoV-2 S1RBD. Samples (or Standards) and biotinylated detection antibody specific for SARS-CoV-2 S1RBD are added to the micro ELISA plate wells. SARS-CoV-2 S1RBD would combine with the specific antibody. Then Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain SARS-CoV-2 S1RBD, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ± 2 nm. The OD value is proportional to the concentration of SARS-CoV-2 S1RBD. You can calculate the concentration of SARS-CoV-2 S1RBD in the samples by comparing the OD of the samples to the standard curve.
This ELISA kit uses the Sandwich-Ag ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with recombinant SARS-CoV-2 Spike Protein. After adding samples (or controls) to wells, the total antibodies against SARS-CoV-2 Spike Protein will combine with the pre-coated SARS-CoV-2 Spike Protein. After washing completely, add Horseradish Peroxidase (HRP) conjugated SARS-CoV-2 Spike Protein to develop the antigen-antibody-HRP conjugated antigen complex. Free components are washed away. The substrate solution is added to each well. Only those wells that contain SARS-CoV-2 Spike Protein, antibodies against SARS-CoV-2 Spike Protein and HRP conjugated SARS-CoV-2 Spike Protein will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ± 2 nm. Compared with the CUT OFF value to judge whether SARS-CoV-2 Spike Protein total antibody exists in the tested samples or not.
