Bioactivity
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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Molecular Weight
54.1 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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
