These newer COVID-19 nucleoprotein Mabs were developed using a recombinant, full-length nucleoprotein and then confirmed that they are reactive with the native virus itself.
Coronavirus Nucleocapsid Antibody is in a phosphate saline buffer (0.01M, pH 7.2) containing 0.1% sodium azide preservative. No stabilizing proteins have been added.

Liquid
Application Notes:
Application Notes: Suggested starting ranges are 1:10-1:50 for IFA and 1:20-1:200 for ELISA. BEST ELISA pairs (capture-conjugate): clones 3865-3866 / 3865-3867 / 3865-3868
Immunohistochemistry Validation of SARS-CoV-2 (COVID-19) Nucleocapsid in COVID-19 Patient Lung. Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti- SARS-CoV-2 (COVID-19) Nucleocapsid antibody (orb1273022, 1 ug/ml). Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT, antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4 C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin. Strong signal of SARS-COV-2 Nucleocapsid protein was observed in the macrophages of COVID-19 patient lung, but not in non-COVID-19 patient lung.
Sandwich ELISA for SARS-CoV-2 (COVID-19) Matched Pair Nucleocapsid Antibodies. Antibodies: SARS-CoV-2 (COVID-19) Nucleocapsid Antibodies, orb1274176 and orb1273022. A sandwich ELISA was performed using SARS-CoV-2 Nucleocapsid antibody (orb1274176, 5 ug/ml) as capture antibody, the Nucleocapsid recombinant protein as the binding protein (orb1231585), and the anti-SARS-CoV-2 Nucleocapsid antibody (orb1273022, 1 ug/ml) as the detection antibody. Secondary: Goat anti-mouse IgG HRP conjugate at 1:20000 dilution. Detection range is from 0.03 ng to 300 ng. EC50 = 2.5 ng
