Sterile Filtered colorless solution.
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 probably 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.
Recombinant Coronavirus 2019-nCoV Spike Glycoprotein-S1 Receptor Binding Domain is a single, glycosylated polypeptide chain containing a total of 232 amino acids (319-541) and having a calculated Mw of 26.2 kDa. CoV-2 S1 (319-541) is fused to a 6 amino acid His-tag at C-terminus,and is purified by proprietary chromatographic techniques.

Measured by its binding ability in a functional ELISA with Human ACE-2.
