Catalogue number



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 HEK293 derived recombinant biotinylated protein contains the Coronavirus 2019 CoV-2 Nucleocapsid, Wuhan-Hu-1 strain, amino acids 1-419 fused to His-Avi tag at C-terminal.


HEK293 Cells.

Purification Method

Purified by Metal-Afinity chromatographic technique.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.


CoV-2 Nucleocapsid protein is supplied in 50mM Tris, 0.15M NaCl & Arginine, pH7.5


Lyophilized Cov-2 Nucleocapsid protein although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CoV2 Nucleocapsid 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.
