Characteristics: Recombinant 2019-nCoV S1 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Val16-Arg685) of 2019-ncov Spike S1 (Accession #YP_009724390.1) fused with a 6xHis tag at the C-terminus.

Purity: >90 % by SDS-PAGE,> 95 % by HPLC

Sterility: 0.22 μm filtered

Endotoxin Level: < 1.0 EU/μg of the protein by LAL method.

Biological Activity Comment: 1.Measured by its binding ability in a functional ELISA. Immobilized Recombinant SARS-CoV-2 Spike S1 at 2 μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 0.5-8.7 ng/mL.< /br>2.Immobilized Human ACE2 on COOH Chip can bind SARS-COV-2 Spike S1 with an affinity constant of 11.4 nM as determined in a SPR assay (Nicoya OpenSPR).

Application Details

Restrictions: For Research Use only

Handling

Format: Lyophilized

Reconstitution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1 % BSA, 5 % HSA, 10 % FBS or 5 % Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.

Buffer: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. or Supplied as a 0.22 μm filtered solution in PBS, pH 7.4.

Handling Advice: Avoid repeated freeze-thaw cycles.

Storage: 4 °C,-20 °C,-80 °C

Storage Comment: Store the lyophilized protein at -20°C to -80 °C for long term.|After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.|or This product is stable at ≤ -70°C for up to 6 months from the date of receipt. |For optimal storage, aliquot into smaller quantities after centrifugation and store at recommended temperature.

Target Details

Target: SARS-CoV-2 Spike S1

Abstract: SARS-CoV-2 Spike S1 Products

Synonyms: E2 Protein, Surface Glycoprotein Protein, S Protein

Target Type: Viral Protein

Background:

Description: 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 thisinteraction.The S protein plays key parts in the induction of neutralizing-antibody and T-cellresponses, as well as protective immunity.
