SARS-COV-2 Spike S1 Protein (D614G, His & Avi)

(Synonyms: Spike,S1 protein, Spike protein S1, S1 protein, S glycoprotein Subunit1) Copy Product Info

Synonyms: Spike,S1 protein, Spike protein S1, S1 protein, S glycoprotein Subunit1

Catalog No. TMPK-00436 Copy Product Info
The SARS-CoV-2 spike (S) protein is the target of vaccine design efforts to end the COVID-19 pandemic. Despite a low mutation rate, isolates with the D614G substitution in the S protein appeared early during the pandemic, and are now the dominant form worldwide. Here, we analyze the D614G mutation in the context of a soluble S ectodomain construct.

Protein Purity
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Endotoxin< 1.0 EU/μg of the protein as determined by the LAL method.
FormulationLyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
ReconstitutionReconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
SynonymsSpike,S1 protein, Spike protein S1, S1 protein, S glycoprotein Subunit1
Research Background
The SARS-CoV-2 spike (S) protein is the target of vaccine design efforts to end the COVID-19 pandemic.

Here, we analyze the D614G mutation in the context of a soluble S ectodomain construct.
Chemical Properties
Molecular Weight77.9 kDa (predicted). Due to glycosylation, the protein migrates to 110-120 kDa based on Tris-Bis PAGE result.
Storage & Solubility Information
ShippingIn general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
StorageIt is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
