Western blot showing specific labeling of SARS-CoV-2 at ~ 25k in green in lane 3. Lane 4 shows GFP-tagged SARS-CoV-2 at ~ 50k in green and lane 2 shows no CoV-2 staining in untransfected cells. The red bands show staining with B-tubulin as a loading control.

SARS-CoV-2 S-Protein ACE2 Binding Domain
The novel SARS-coronavirus 2 (SARS-CoV-2) which causes the disease COVID-19 has been shown to utilize the SARS-CoV receptor ACE2 for entry into human cells (Hoffman, M. et al., Cell 2020). The entry of a coronavirus into host cells is mediated by the viral surface-anchored transmembrane spike (S) glycoprotein which is composed of two functional subunits, S1 which binds the receptor and S2 which fuses the membrane (Walls, AC et.al., Cell 2020). S1 contains a receptor-binding domain (RBD) which specifically recognizes ACE2 as its receptor (Wan, Y. et al., 2020).
Antigen Affinity Purified
25 kDa or 142 kDa full-length
Recombinant SARS-CoV-2 S-Protein construct containing the ACE2 binding domain expressed in and purified from E. coli.
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
The antibody was purified over a column to which the protein antigen was coupled.
PBS + 50% glycerol and 5 mm NaN3
Specific for the ~25 kDa ACE2 binding domain construct of SARS-CoV-2 S protein. Full-length CoV-2 S protein is ~142 kDa.
Western blots performed on each lot.
