SARS-CoV-2 Spike S1
|Name||SARS-CoV-2 Spike S1|
cDNA encodes SARS-CoV-2 surface protein (YP_009724390.1)
Protein contains amino acids 14-681, two extra amino acids (AS) in N-terminus and His-6 tag at C-terminus.
CHO-based cell line (expressed by QMCF Technology)
Metal-affinity chromatography following gel filtration. Protein is sterile-filtrated
through 0.22 µm filter.
PBS pH 7.4
|Bioproperties||Measured by its binding ability to ACE2 protein by OCTET RED96 system.|
Shipped on dry-ice
Store at -70°C upon receipt. Recommended to aliquot into smaller quantities. Avoid repeated freeze-thaw cycles
Figure 2. Binding analysis of the SARS-CoV-2 Spike S1 protein to hACE2 receptor. hACE2 -Fc protein was bound to Protein G sensor. 25 to 200 nanomols of SARS-CoV-2 Spike S1 protein was bound to the ACE2 receptor.
