| Amount : | 100 μg |
| Purification : | Protein is >90% pure as determined SDS-PAGE. |
| Content : | CoV-2 S1 protein is supplied in 1x PBS pH-7.4 & 5% trehalose. |
| Storage condition : | Lyophilized Cov-2 Spike S1 Glycoprotein although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CoV2 Spike 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). Prevent freeze-thaw cycles. |
| AA sequence : | The HEK293 derived recombinant protein contains the Coronavirus 2019 CoV-2 Spike Glycoprotein S1, Wuhan-Hu-1 strain, amino acids 16-685 fused to His tag at C-terminal. |
Source: HEK293 cells. 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.
