| Protein Name / Synonyms | Spike protein, S Protein, S1 Subunit |
| Expressed Region | Tyr18-Glu725 |
| Expression System | HEK293 cells |
| Tag | C-terminal his-tag |
| Purification | His-tag affinity purification by immobilized metal ion affinity chromatography (IMAC) |
| Purity | >95 % |

| Molecular Weight (kDa) | Recombinant protein product has a calculated molecular mass of ∼80 kDa. Due to the abundant glycosylation, it migrates as approximately 120 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. After deglycosylation under native and denature conditions, the protein presented as one reduced ∼80 kDa band. See deglycosylation analysis image below. |
| Format | Liquid |
| Formulation | Supplied as a 0.2 µm filtered solution in PBS (pH 7.4) |
| Concentration (lot specific) | Lot specific (see the label on the vial), determined by BCA protein assay |
| Endotoxin Level | < 0.5 EU per µg of the protein as determined by the LAL method |
| Estimated Lead Time | 1-2 business days |
| Shipping Type | Blue ice |
| Storage | -20°C |
