The coronavirus nucleocapsid protein is the major structural component of virions that associates with genomic RNA to form a long, flexible, helical nucleocapsid.  Sequence comparison of the N genes of five strains of the coronavirus mouse hepatitis virus suggests a three-domain structure for the nucleocapsid protein. Anti-SARS-CoV Nucleocapsid (N) Protein Antibody is useful for researchers interested in viral research.

Target Details

Recombinant Protein
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a purified recombinant protein corresponding to full length SARS Coronavirus Nucleocapsid protein.
Anti-SARS-CoV-1 (N) affinity purified antibody is directed against SARS Coronavirus Nucleocapsid (N) protein. The product was purified from monospecific antiserum by immunoaffinity chromatography over SARS CoV-2 (N) resin. Detects the Nucleocapsid (N), Omicron, and BA.2 sub-variant. BLAST analysis was used to suggest reactivity with related Coronavirus proteins.  Cross reactivity with homologues from other sources has not been determined.

Application Details

Other  - View References
Anti-SARS-CoV-1 purified antibody has been tested for use in ELISA, immunofluorescence, and western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 46 kDa in size corresponding to SARS Nucleocapsid (N) protein by western blotting in the appropriate cell lysate or extract. This antibody can be useful in ELISA and lateral flow format to detect virus in extracts from nasal and throat swabs and saliva. IF can be been useful to determine the presence or absence of virus entering cells especially when anti-viral drugs are applied. IHC studies can be performed on biopsies, detecting the coronavirus in lung, liver, bile duct, and placenta tissue. And may have the ability to neutralize the virus and thereby protect cells from the uptake of live virus. This antibody may be useful in flow cytometry studies.
