Recombinant SARS-CoV-2 Spike S1 Protein (RP01280)

Datasheet

ABclonal:Recombinant SARS-CoV-2 Spike S1 Protein

Overview

Product name Recombinant SARS-CoV-2 Spike S1 Protein
Catalog No. RP01280
Description Recombinant SARS-CoV-2 Spike S1 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Val16-Arg685) of sars-cov-2 Spike S1 (Accession #YP_009724390.1) fused with a mFc tag at the C-terminus.
Bio-Activity Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human ACE2-His Protein at 2 μg/mL (100 μL/well) can bind Recombinant SARS-CoV-2 Spike S1-mFc Protein, the EC50 of Recombinant SARS-CoV-2 Spike S1-mFc Protein is 79.21 ng/mL.
Purity > 85% by SDS-PAGE.
Endotoxin < 0.1 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 liquid product is stable at ≤ ‑70°C for up to 1 year from the date of receipt.
For optimal storage, aliquot into smaller quantities after centrifugation and store at recommended temperature.
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.
