| Description | Recombinant human B7-1 protein with C-terminal human Fc tag |
| Delivery | In Stock |
| Uniprot ID | P33681 |
| Expression Host | HEK293 |
| Tag | C-Human Fc Tag |
| Molecular Characterization | B7-1(Val35-Asn242) hFc(Glu99-Ala330) |
| Molecular Weight | The protein has a predicted molecular mass of 50.0 kDa after removal of the signal peptide. |
| Purity | The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. |
| Formulation & Reconstitution | Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions of reconstitution. |
| Storage & Shipping | Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature. |
| Background | The protein encoded by this gene is a membrane receptor that is activated by the binding of CD28 or CTLA-4. The activated protein induces T-cell proliferation and cytokine production. This protein can act as a receptor for adenovirus subgroup B and may play a role in lupus neuropathy. |
