Bioactivity Data: ①Measured by ACE2 protein (CSB-MP866317HU) binding ability in a functional ELISA.
Coat the plate with 0.2ug/well (2ug/ml, 100ul/well) of SARS-CoV-2 S1 protein (CSB-MP3324GMY), add 100ul/well (0.7629-100000ng/ml, gradient dilution, 2x to 18x) of ACE2 protein and 100ul/well of Peroxidase-Affinipure Goat Anti-Human IgG, Fcγ Fragment Specific (CSB-PA160506). Wells were washed with buffer, and then A450 nm was measured. The results showed SARS-CoV-2 S1 protein could bind ACE2 protein. The EC50 is 56.64 – 103.6 ng/ml.

⑤The SPR sensorgram shows the binding between ACE2 protein (CSB-MP866317HU) and SARS-CoV-2 S1-RBD protein (CSB-YP3324GMY1).
ACE2 protein was injected at 5 concentrations (400, 200, 100, 50, 0 nM) across 0.5 mg/ml of SARS-CoV-2 S1-RBD protein captured on a COOH chip. The results showed ACE2 protein could bind SARS-CoV-2 S1-RBD protein with an affinity constant of 100 nM.
⑥The SPR sensorgram shows the binding between ACE2 protein (CSB-MP866317HU) and SARS-CoV-2 S1-RBD protein (CSB-MP3324GMY1b1).
