Catalogue number



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 HEK293 derived recombinant protein contains the SARS Coronavirus spike S glycoprotein Receptor Binding Domain, amino acids 306-527 fused to His tag at C-terminal.



Purification Method

Purified by immobilized metal affinity chromatographic technique.

Physical Appearance

Lyophilized freezed dried powder.


SARS Spike S glycoprotein RBD is lyophilized from 1x PBS pH-7.4 + 5% trehalose.


SARS Spike S1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution SARS Spike protein should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.


Protein is >90% pure as determined SDS-PAGE.
