Mol. Weight: 54.1 kDa

Purity: Greater than 85% as determined by SDS-PAGE.

Endotoxin: Less than 1.0 EU/ug as determined by LAL method.

Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized human ACE2 at 2 μg/ml can bind Biotinylated-SARS-CoV-2-S1-RBD (CSB-MP3324GMY1-B), the EC50 is 5.087-7.050 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.
