- Restrictions
- For Research Use only
-
- Format
- Lyophilized
- Reconstitution
- Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
- Buffer
- Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
- Storage
- 4 °C,-80 °C
- Storage Comment
- Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
- Expiry Date
- 12 months

- SARS-CoV-2 Spike S1
- Alternative Name
- SARS-CoV Spike S1 (SARS-CoV-2 Spike S1 Products)
- Synonyms
- E2 Protein, Surface Glycoprotein Protein, S Protein
- Background
- S1 protein, Spike protein S1, Spike,S1 protein, S glycoprotein Subunit1,The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
- Molecular Weight
- 100.6 kDa. Due to glycosylation, the protein migrates to 120-140 kDa based on Tris-Bis PAGE result.
- UniProt
