Spike glycoprotein, S glycoprotein, Peplomer protein, E2 glycoprotein precursor, Severe acute repiratory Syndrome-related Coronavirus, SARS, SRAS-CoV, SARS-CoV1, E2.
SARS Coronavirus is an enveloped virus containing 3 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 takes part in virus infection cycle and is the primary target of neutralizing antibodies.
SARS Spike produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 1188 amino acids (14-1195 aa) and having a molecular mass of 131.9kDa.
SARS Spike is fused to a 6 amino acid His tag at C-terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
The SARS Spike (14-1195) solution (0.25mg/ml) contains Phosphate-Buffered Saline (pH 7.4) and 10% Glycerol.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 85.0% as determined by SDS-PAGE.
Measured by its binding ability in a functional ELISA with Human ACE-2 (CAT# enz-1159).
