![Immunohistochemistry-Paraffin: SARS-CoV-2 3CL Protease Antibody [NBP3-07062] - Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti- SARS-CoV-2 3CL protease antibody (0.5 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 4C. 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 3L-PRO (NSP5) protein was observed in macrophage of COVID-19 patient lung, but not in non-COVID-19 patient lung.](http://images.novusbio.com/fullsize/SARS-CoV-2-3CL-Protease-Antibody-Immunohistochemistry-Paraffin-NBP3-07062-img0002.jpg)
