• Bioactivity: ①Measured by ACE2 protein (CSB-MP866317HU) binding ability in a functional ELISA. Coat the plate with 0.2μg/well (2μg/ml, 100μl/well) of SARS-CoV-2 S1 protein (CSB-MP3324GMY), add 100μl/well (0.7629-100000ng/ml, gradient dilution, 2x to 18x) of ACE2 protein and 100μl/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. ②Measured by ACE2 protein (CSB-MP866317HU) binding ability in a functional ELISA. Coat the plate with 0.5μg/well (5μg/ml, 100μl/well) of SARS-CoV-2 S1-RBD protein (CSB-YP3324GMY1), add 100μl/well (0.762939-100000ng/ml, gradient dilution, 2x to 18x) of ACE2 protein and 100μl/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-RBD protein could bind ACE2 protein. The EC50 is 31.80 - 44.69 ng/ml. ③Measured by ACE2 protein (CSB-MP866317HU) binding ability in a functional ELISA. Coat the plate with 0.5μg/well (5μg/ml, 100μl/well) of SARS-CoV-2 S1-RBD protein (CSB-MP3324GMY1b1), add 100μl/well (0.762939-100000ng/ml, gradient dilution, 2x to 18x) of ACE2 protein and 100μl/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-RBD protein could bind ACE2 protein. The EC50 is 2.785-9.139 ng/ml. ④Measured by ACE2 protein (CSB-MP866317HU) binding ability in a functional ELISA. Coat the plate with 0.2μg/well (2μg/ml, 100μl/well) of ACE2 protein, add 100μl/well (0.00001164153-200000ng/ml, gradient dilution, 4x to 18x) of SARS-CoV-2 S1-RBD protein (CSB-MP3324GMY1) and 100μl/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-RBD protein could bind ACE2 protein. The EC50 is 8.363-12.82 ng/ml 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). ACE2 protein was injected at 5 concentrations (100, 50, 25, 12.5, 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 13.8 nM.
• Length: Partial
• Form: Lyophilized powder
• Buffer: Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
• Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
• Molecular Weight: 112.5 kDa
• Storage Conditions: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
