Expressed In: HEK293 cells Protein Species: SARS-CoV-2 Research Area: COVID-19 Description
Recombinant SARS-CoV-2 Spike RBD Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Arg319-Phe541) of 2019-ncov Spike RBD (Accession #YP_009724390.1) fused with an mFc tag at the C-terminus.Bio-Activity
Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human ACE2 Protein at 2ug/mL (100 uL/well) can bind Recombinant SARS-COV-2 Spike RBD-mFc Protein. The EC50 of Recombinant SARS-COV-2 Spike RBD-mFc Protein is 2.58 ng/mLPurity
> 95% by SDS-PAGE.Endotoxin
< 0.1 EU/ug of the protein by LAL method.Formulation
Lyophilized from a 0.22 um filtered solution of PBS, pH 7.4. or Supplied as a 0.22 um filtered solution in PBS, pH 7.4.4Species

Storage
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 the recommended temperature.
Reconstitution
For lyophilized protein: Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.Alternative Names
S1-RBD protein; NCP-CoV RBD Protein; novel coronavirus RBD Protein; 2019-nCoV RBD Protein; S glycoprotein Subunit1 RBD Protein; SARS-CoV-2; 2019-nCoV -
