<strong>Figure 1 Immunohistochemistry Validation of SARS-CoV-2 (COVID-19) NSP2 in COVID-19 Patient Lung</strong><br> Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti- SARS-CoV-2 (COVID-19) NSP2 antibody (9173, 0.5 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. Strong signal of SARS-COV-2 NSP2 protein was observed in macrophage of COVID-19 patient lung, but not in non-COVID-19 patient lung.
<strong>Figure 2 ELISA Validation with SARS-CoV-2 (COVID-19) NSP2 Protein </strong><br>Antibodies: SARS-CoV-2 (COVID-19) NSP2 Antibody, 9173 A direct ELISA was performed using SARS-CoV-2 NSP2 recombinant protein (10-425) as coating antigen and the anti-SARS-CoV-2 (COVID-19) NSP2 antibody as the capture antibody Secondary: Goat anti-rabbit IgG HRP conjugate at 1:20000 dilution. Detection range is from 1 ng/mL to 3000 ng/mL.

Background:
Coronavirus disease 2019 (COVID-19), formerly known as 2019-nCoV acute respiratory disease, is an infectious disease caused by SARS-CoV-2, a virus closely related to the SARS virus (1). The disease is the cause of the 2019–20 coronavirus outbreak (2). The structure of 2019-nCoV consists of the following: a spike protein (S), hemagglutinin-esterease dimer (HE), a membrane glycoprotein (M), an envelope protein (E) a nucleoclapid protein (N) and RNA. NSP2 may play a role in the modulation of host cell survival signaling pathway by interacting with host PHB and PHB2. Indeed, these two proteins play a role in maintaining the functional integrity of the mitochondria and protecting cells from various stresses (3).
