Recombinant human Angiotensin-converting enzyme 2 (ACE2) expressed in HEK293 cells. Extracellular domain of human ACE2 (aa 18-740) are fused at the C-terminus to a FLAG®-tag. Molecular weight: ~110kDa (SDS-PAGE); ~240kDa (Dimer, by SEC).
ACE2 Human, HEK293 Recombinant binds with high affinity to the Spike S1RBD protein of the virus SARS-CoV-2.
ACE2 Human, HEK293 Recombinant was coated on an ELISA plate at 1μg/ml overnight at 4°C. Recombinant SARS-CoV-2 Spike Protein S1RBD was added (starting at a concentration of 500ng/ml with a two-fold serial dilution) during one hour at RT and the interaction was then detected using an anti-human IgG (HRP).
<0.01 EU/μg (LAL test).
1 mg/ml after reconstitution. Lyophilized. Contains PBS.
Reconstitute with 50 μl endotoxin-free water.
