Monoclonal Mouse Affinity Purified E B IF
The Coronaviridae virus family is characterized by a nucleocapsid that is composed of the genome RNA molecule in combination with the nucleoprotein (N protein) within a virion. The N protein (nucleoprotein) is one of the major structural proteins in a viral particle, playing a critical role in the transcription regulation of the genomic RNA and other viral proteins. It might also be involved in the virulence and virus-specific post-translational modifications. The N protein is composed of 422 amino acids (a.a.) with an estimated molecular weight of 46.03 kD. The most striking physiochemical feature of the N protein of SARS-CoV is that it is a typical basic protein with a high predicted pI and high hydrophilicity, which is consistent with its function of binding to the ribophosphate backbone of the RNA molecule. The N protein contains multiple candidate phosphorylation sites, suggesting that it may be related to important functions, such as
RNA-binding and localization to the nucleolus of host cells. Subsequent study shows that there is an SR-rich region in the N protein and this region might be involved in the protein-protein interaction. The abundant antigenic sites predicted in the N protein, as well as experimental evidence with synthesized polypeptides, indicate that the N protein is one of the major antigens of the SARS-CoV. Compared with other viral structural proteins, the low variation rate of the N protein with regards to its size suggests its importance to the survival of the virus.
Catalog #S0098-19
ApplicationsSuitable for use in Immunofluorescence, Western Blot and ELISA. Other applications have not been tested.
Recommended DilutionImmunofluorescence: 1-5ug/ml
Western Blot: 1-5ug/ml
ELISA: 0.1-2ug/ml
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
