| Species: | SARS-CoV-2/2019-nCoV |
| Molecular mass: | 38.2 kDa |
| Research areas: | Microbiology |
| Activity: | Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1 (D614G) at 2 μg/ml can bind human ACE2 (Catalog number: D140021), the EC50 is 8.236-11.22 ng/ml. |
| Endotoxin: | Less than 1.0 EU/ug as determined by LAL method. |
| 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. |
| Background: | The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. |
