Description

General description

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.
Recombinant SARS-COV-2 S1+S2 ECD (S-ECD) Protein with His tag (Wild type, pre-fusion state plus post-fusion state) 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 6XHis tag at the C-terminus.

Biochem/physiol Actions

Measured by its binding ability in a functional ELISA. Immobilized Recombinant SARS-COV-2 Spike S1+S2 ECD-His at 2μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 0.15-9.92 ng/mL.

Preparation Note

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. Avoid repeated freeze-thaw cycles.
