| Expression Region | 319-541aa (G476S) |
| Sequence Info | Partial |
| Source | Mammalian cell |
| Tag Info | C-terminal 10xHis-tagged |
| MW | 27.9 kDa |
| Lead Time | 3-7 business days |
| Distributor Price 2 | 100ug |
| Purity | Greater than 90% as determined by SDS-PAGE. |
| Biological Activity | Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD (G476S) at 5 ?g/ml can bind human ACE2 (CSB-MP866317HU), the EC50 is 47.11-92.3 ng/ml. |
| Storage Buffer | Lyophilized from a 0.2 ?m filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0 |
| Storage | 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?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?. |
| Endotoxin | Less than 1.0 EU/ug as determined by LAL method. |
