Product Description
Specifications
| Size | 50 µg, 200 µg |
| Estimated Lead Time | 2-3 business days |
| Species | MERS-CoV |
| Accession Number | K0BRG7 |
| Gene Symbols | S |
| Protein Name / Synonyms | Spike protein, S Protein, S1 Subunit |
| Expressed Region | Tyr18-Glu725 |
| Expression System | HEK293 cells |
| Conjugation | Biotin |
| Tag | C-terminal his-tag. The primary amino groups (-NH2) at the N-terminus and the side chains of lysine (K) residues were biotin-conjugated using the standard chemical labeling method. |
| Purity | >95% |
| Purity Determined By | SDS-PAGE under reducing conditions and visualized by Coomassie blue staining |
| 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 |
| Research Area | Infectious Disease, MERS |
| Protein Type | Recombinant Protein |
| Shipping Type | Blue ice |
| Storage | -20°C |
