SARS Coronavirus is an enveloped virus containing three outer structural proteins, namely the membrane (M), envelope (E), and spike (S) proteins. Spike (S)-glycoprotein of the virus interacts with a cellular receptor and mediates membrane fusion to allow viral entry into susceptible target cells. Accordingly, S-protein plays an important role in virus infection cycle and is the primary target of neutralizing antibodies.
The E.Coli derived 32 kDa recombinant protein contains the Nucleocapsid core protein 1-49 amino acids immunodominant regions.
The SARS Core protein was purified by proprietary chromatographic technique.
SARS Core protein is >95% pure as determined by 10% PAGE (coomassie staining).
50mM Tris-HCl, 60mM NaCl and 50% glycerol.
SARS Core protein is shipped at ambient temperature.
Upon arrival, store at -20C.
SARS Core protein is Immunoreactive with sera of SARS-infected individuals.
SARS Core antigen is suitable for ELISA and Western blots, excellent antigen for detection of SARS with minimal specificity problems.
