Measured by its binding ability in a functional ELISA. Immobilized human ACE2, His-Avi Tag (Cat: orb1516578) at 2 µg/mL (100 µl/Well) can bind SARS-CoV-2 Spike trimer Protein (His Tag) (Omicron/B.1.1.529) (Cat: orb1516626), the EC50 is 1.5 µg/mL.

Measured by its binding ability in a indirect ELISA. Immobilized SARS-CoV-2 Spike trimer Protein (His Tag) (Omicron/B.1.1.529) (Cat: orb1516626) at 2 µg/mL (100 µl/Well) can bind Anti-SARS-CoV-2 Spike Monoclonal antibody.

The purity of the protein is greater than 90% as determined by reducing SDS-PAGE.
