Product Specifications

Immunogen

The antibody was developed by immunizing Rabbit with a synthetic peptide corresponding to amino acids 399-411 (DLDDFSKQLQQSM-C) from the N (SARS Nucleocapsid) for the Human SARS coronavirus (Genbank accession no. YP_009724397.2)

Reactivity Notes

Use in SARS-CoV-2 reported in scientific literature (PMID:33807059).

Specificity

Dot Blot results using recombinant proteins for cross-reactivity testing revealed high reactivity to SARS-CoV-2 Nucleocapsid protein (NBP2-90975) and low/no reactivity towards H1N1 (NBP1-99041). No cross-reactivity observed with influenza A(H1N1) virus, influenza B virus, respiratory syncytial virus, parainfluenza virus type 3, human coronavirus (HCoV) 229E, or MERS-CoV in PCR-confirmed tissue samples [PMID:32437316].

Background: SARS Nucleocapsid Protein

It has recently been shown that SARS is caused by a human coronavirus. Human coronaviruses are the major cause of upper respiratory tract illness in humans, such as the common cold. Coronaviruses are positive-stranded RNA viruses, featuring the largest viral RNA genomes known to date (27-31 kb). The first step in coronavirus infection is binding of the viral spike protein, a 139-kDa protein, to certain receptors on host cells. The spike protein is the main surface antigen of the coronavirus. The most prominent protein in the culture supernatants infected with SARS virus is a 46 kDa nucleocapsid protein. This suggests that the nucleocapsid protein is a major immunogen that may be useful for early diagnostics.

FAQs for SARS Nucleocapsid Protein Antibody - BSA Free

Showing  1 - 1 of 1 FAQ Showing All

  • Q: does your antibody NB100-56576 recognizes SARS-CoV-2 or only SARS-Cov? (Image 1 indicates Cov2 in the legend, but the data sheet only states SARS coronavirus

    A:

    This antibody was originally developed against SARS, but due to identity to SARS-CoV-2 was predicted to cross-react. the image in question (#1) is from a recent publication that used NB100-56576 to detect SARS-CoV-2 nucleocapsid. Here is the link to the publication if you would like to take a look https://www.biorxiv.org/content/10.1101/2020.03.21.001628v1
