SARS-CoV-2 nsp9 Antibody - BSA Free

Immunohistochemistry: SARS-CoV-2 nsp9 Antibody [NBP3-07044] - Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti- SARS-CoV-2 (COVID-19) NSP9 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 4 degrees celsius. 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 NSP9 protein was observed in macrophage of COVID-19 patient lung, but not in non-COVID-19 patient lung.

ELISA: SARS-CoV-2 nsp9 Antibody [NBP3-07044] - Antbodies: SARS-CoV-2 (COVID-19) NSP9 Antibody. A direct ELISA was performed using immunogen peptide (9161P) as coating antigen and the anti-SARS-CoV-2 (COVID-19) NSP9 antibody as the capture antibody. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:20000 dilution. Detection range is from 0.3 ng/mL to 1000 ng/mL.

Background

SARS-CoV-2 Nonstructural Protein 9 (NSP9) is one of the sixteen nonstructural proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19 (1). SARS-CoV-2 NSP9 is 113 amino acids (aa) with a theoretical molecular weight of 12.4 kDa (1-3). The amino acid sequence alignment of SARS-CoV and SARS-CoV-2's NSP9 has 97.3% sequence identity and 99.1% sequence similarity (1). Structurally NSP9 has a N-terminal beta-barrel made of seven beta-strands and a C-terminal alpha-helix (3). In SARS-CoV, NSP9 is important for viral proliferation; it is unclear if NSP9 plays the same role in SARS-CoV-2 but given the high degree of sequence similarity it is quite likely (4). SARS-CoV-2 NSP9 also plays a role in formation of nuclear transport machinery and the extracellular matrix (2). Additionally, NSP9 binds mind bomb 1 (MIB1), an E3 ubiquitin ligase that regulates antiviral innate immune signaling (2).
