Overview
Product name Active Recombinant SARS-CoV-2 Spike S1(D614G) Protein Catalog No. RP01287 Description Recombinant SARS-CoV-2 Spike S1(D614G) Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Val16-Arg685(Asp614Gly)) of sars-cov-2 Spike S1(D614G) (Accession #QHD43416.1) fused with a 6×His tag at the C-terminus. Bio-Activity 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 0.03-6.26 ng/mL. Purity > 95% by SDS-PAGE. Endotoxin < 1.0 EU/μg of the protein by LAL method. Formulation Supplied as a 0.22 μm filtered solution in PBS, pH 7.4 or Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
