Biological Activity: ①Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 2 μg/ml can bind SARS-CoV-2-S Antibody (CSB-RA33245A1GMY), the EC50 of SARS-CoV-2-S1-RBD protein is 27.96 - 33.35 ng/ml. ②Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 2 μg/ml can bind SARS-CoV-2-S Antibody (CSB-RA33245A0GMY), the EC50 of SARS-CoV-2-S1-RBD protein is 13.96 -16.62 ng/ml. ③Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 5 μg/ml can bind human ACE2 (CSB-MP866317HU), the EC50 is 2.785-9.139 ng/ml. ④SARS-CoV-2 Spike protein RBD his/myc tag (CSB-MP3324GMY1b1) captured on COOH chip can bind Human ACE2 protein Fc tag (CSB-MP866317HU) with an affinity constant of 13.8 nM as detected by LSPR Assay. ⑤Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 2 μg/ml can bind Biotinylated human ACE2 (CSB-MP866317HU-B), the EC50 is 4.599-8.322 ng/ml.

Form: Lyophilized powder

Buffer: Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0

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.
