| Description |
CUSABIO expressed the bovine coronavirus (BCoV) spike glycoprotein (S) amino acid residues Pro326-Thr540 carrying an N-terminal 6xHis-tag in E.coli.The product is the recombinant partial-length BCoV-S protein. Its purity is greater than 90% determined by SDS-PAGE. The observed molecular mass was approximately 28 kDa, slightly higher than the calculated one (27.7 kDa). In addition to producing specific antibodies, this BCoV-S protein may be used to study microbiology. |

| Form |
Liquid or Lyophilized powder Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand. |
| Buffer | If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 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. |
| Troubleshooting and FAQs |
Protein FAQs |
| Storage Condition | Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles. |
| Shelf Life | 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. |
| Lead Time | 13-23 business days |
| Notes | Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week. |

| Function (From Uniprot) |
S1 attaches the virion to the cell membrane by binding to 9-O-acetylated sialic acid containing proteins, initiating the infection. |
| Subcellular Location | Spike protein S2: Virion membrane, Single-pass type I membrane protein, Host endoplasmic reticulum-Golgi intermediate compartment membrane, Single-pass type I membrane protein, Note=Accumulates in the endoplasmic reticulum-Golgi intermediate compartment, where it participates in virus particle assembly, Some S oligomers may be transported to the plasma membrane, where they may mediate cell-cell fusion (By similarity), SUBCELLULAR LOCATION: Spike protein S1: Virion membrane, Peripheral membrane protein, Host endoplasmic reticulum-Golgi intermediate compartment membrane, Peripheral membrane protein |
| Protein Families | Betacoronaviruses spike protein family |
