SARS-CoV-2 (COVID-19) NSP2 Antibody

Infectious Disease, COVID-19

Anti-SARS-CoV-2 (COVID-19) NSP2 antibody (9173) was raised against a peptide corresponding to 15 amino acids near the center of SARS-CoV-2 (COVID-19) NSP2 protein.

The immunogen is located within 50-100 amino acids of the SARS-CoV-2 (COVID-19) NSP2 protein.

SARS-CoV-2 (COVID-19) NSP2 Antibody is affinity chromatography purified via peptide column.

IgG

SARS-CoV-2 (COVID-19) NSP2 Antibody is supplied in PBS containing 0.02% sodium azide.

SARS-CoV-2 (COVID-19) NSP2 antibody can be stored at 4 ˚ C for three months and -20 ˚ C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.

Optimal dilutions/concentrations should be determined by the end user. The information provided is a guideline for product use. This product is for research use only.

Severe acute respiratory syndrome coronavirus 2

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).

Figure 1 Immunohistochemistry Validation of SARS-CoV-2 (COVID-19) NSP2 in COVID-19 Patient Lung
Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti- SARS-CoV-2 (COVID-19) NSP2 antibody (9173, 0.5 μ g/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.
