Immunohistochemistry Validation of SARS-CoV-2 (COVID-19) Nucleocapsid in Human Lung Tissue from the COVID-19 Patient (Sun et al., 2020). Detection of SARS-CoV-2 nucleocapsid protein by anti-SARS-COV-2 nucleocapsid antibodies (orb1239972, 0.02 µg/mL, A,B) or SARS-CoV-2 Spike S1 antibodies (orb1239995, 1 µg/mL D,E) in adjacent sections of autopsy lung tissue from COVID-19 deceased patient. Negative control staining on autopsy lung tissue from patient who died from non-COVID-19 pneumonia is shown for Nucleocapsid protein (C) or Spike protein (F). Negative control using normal rabbit immunoglobulin on COVID-19 autopsy tissue is presented (G). DAB chromogen and hematoxylin counterstain are used. Scale bars: 50µM in A, C, D, F, G, 20 µM in B and E.
Immunohistochemistry Validation of SARS-CoV-2 (COVID-19) Nucleocapsid in Human Lung Tissue from the COVID-19 Patient. Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti-SARS-CoV-2 (COVID-19) Nucleocapsid antibody (orb1239972, 0.02 µg/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.
