|Product name||Recombinant Human ACE-2 Protein|
|Description||Recombinant Human ACE2 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gln18-Ser740) of human ACE2 (Accession #Q9BYF1) fused with a 6×His，Avi tag at the C-terminus.|
|Bio-Activity||Measured by its binding ability in a functional ELISA. Immobilized Human ACE2-His at 2 μg/mL (100 μL/well) can bind Recombinant SARS-CoV-2 Spike S1 with a linear range of 0.064-50.77 ng/mL.|
|Purity||> 95% by SDS-PAGE.|
|Endotoxin||< 1.0 EU/μg of the protein by LAL method.|
|Formulation||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.Contact us for customized product form or formulation.|
|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 recommended temperature.
|Reconstitution||For lyophilized protein : Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.|
