ABclonal:Active Recombinant SARS-COV-2 Spike S1+S2 ECD(S-ECD) Protein


Product nameActive Recombinant SARS-COV-2 Spike S1+S2 ECD(S-ECD) Protein
Catalog No.RP01260LQ
DescriptionActive Recombinant SARS-COV-2 Spike S1+S2 ECD(S-ECD) Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Val11-Gln1208) of SARS-COV-2(2019-nCoV) S1+S2 ECD (S-ECD) (Accession #YP_009724390.1) fused with a 6×His tag at the C-terminus.
Bio-ActivityMeasured by its binding ability in a functional ELISA. Immobilized Recombinant SARS-CoV-2 Spike S1+S2 ECD-His at 2 μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 0.15-9.92 ng/mL.
Purity>97% by SDS-PAGE.
Endotoxin< 0.1 EU/μg of the protein by LAL method.
FormulationSupplied as a 0.22 μm filtered solution in PBS, pH 7.4.Contact us for customized product form or formulation.Contact us for customized product form or formulation.
Calculated MW133.8kDa
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.
