Product Details


Novel Coronavirus 2019 Spike Nucleocapsid-Mosaic, recombinant.


Description of SARS-CoV-2 Spike N-Mosaic (nCoV-S2 Spike N-Mosaic, His-Tag)

Recombinant SARS-CoV-2 spike Nucleocapsid Mosaic immunodominant protein (Full length N-Antigen) is derived from E. coli and fused to a His-tag at the C-terminal end. SARS-CoV-2, formerly termed 2019-nCOV, causes the pandemic COVID-19 disease, a viral pneumonia.

The SARS-CoV-2 shares an 87% identity to two bat-derived severe acute respiratory syndrome 2018 (SARS-like) coronaviruses found in Zhoushan of eastern China. It is more distant from SARS-CoV (79%) identity and MERS-CoV (50%) identity. SARS-CoV-2 has an analogous receptor-binding domain-structure to that of 2018 SARS-CoV, even though there is a.a. diversity so thus the 2019-nCoV might bind to ACE2 receptor protein (angiotensin-converting enzyme 2) in humans.

While bats are possibly the host of SARS-CoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the SARS-CoV-2 is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.



The protein is stable for at least 2 weeks at 0°C - 4°C, and therefore can be shipped on ice packs. Upon arrival it should be stored at -20 °C. Please avoid repeated freeze thaw cycles.
