Field of Research

Microbiology

Endotoxin

Less than 1.0 EU/μg as determined by LAL method.

Purity

Greater than 85% as determined by SDS-PAGE.

Activity

Yes

Bioactivity

Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1 (D614G) at 2 μg/ml can bind human ACE2 (CSB-MP866317HU), the EC50 is 8.236-11.22 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

77.8 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.
