A human infecting coronavirus (viral pneumonia) called 2019 novel coronavirus, 2019-nCoV was found in the fish market at the city of Wuhan, Hubei province of China on December 2019.

The 2019-nCoV shares an 87% identity to the 2 bat-derived severe acute respiratory syndrome 2018 SARS-CoV-2 located in Zhoushan of eastern China. 2019-nCoV has an analogous receptor-BD-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 2019-nCoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the 2019-nCoV is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.

The recombinant Coronavirus 2019 CoV-2 Spike Glycoprotein S1, Wuhan-Hu-1 strain containing a total of 680 amino acids (16-685) and having a calculated Mw of 76.2 kDa. CoV-2 S1 (16-685)  is fused to a 6 amino acid His-tag at C-terminus,and is purified by proprietary chromatographic techniques.

HEK293 Cells.

The  CoV-2 S1 (16-685) 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 (enz-1125).
