| Cat.No. : |
S1-137V |
| Product Overview : |
Recombinant COVID-19 Spike protein (16-685aa) was fused to His-tag at the N-terminus and expressed in Yeast. |
| Description : |
It's been reported that Coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity. |

| Purity : |
Greater than 90% as determined by SDS-PAGE. |
| Storage : |
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. |
| Reconstitution : |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference. |
| Handling : |
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week. |
| SDS-PAGE of S1-137V : |
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
Predicted band size: 88.1 kDa
Observed band size: 100 kDa due to glycosylation
