COVID 19 Spike Glycoprotein-S1 Coronavirus (COVID-19) Coronavirus Recombinant Protein

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 E Coli derived recombinant protein contains the Coronavirus 2019 Spike S1 (200-800 a.a.) region, fused to 6xHis tag at C-terminal

Small volumes of COVID-19 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS141689 is a recombinant protein targeting COVID-19. Also known as Recombinant Coronavirus 2019-nCoV Spike Glycoprotein-S1 (20-800 a.a.). Host: E Coli.
