| Product Name: Human CD70 Protein |
| Size : 10 µg, 50 µg and 100 µg |
| Synonyms: CD70;D27LG;NFSF7;NFSF7G;D27L |
| Target: CD70 |
| UNIPROT ID: P32970 |
| Description: Recombinant human CD70 protein with C-terminal human Fc and 6xHis tag |
| Background: The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for TNFRSF27/CD27. It is a surface antigen on activated, but not on resting, T and B lymphocytes. It induces proliferation of costimulated T cells, enhances the generation of cytolytic T cells, and contributes to T cell activation. This cytokine is also reported to play a role in regulating B-cell activation, cytotoxic function of natural killer cells, and immunoglobulin sythesis. |
| Species/Host: HEK293 |
| Molecular Weight: The protein has a predicted molecular mass of 44.1 kDa after removal of the signal peptide. |
| Molecular Characterization: CD70(Gln39-Pro193) hFc(Glu99-Ala330) 6×His |
| Purity: The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. |
| Formulation & Reconstitution: Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% – 8% trehalose is added as protectants before lyophilization. |
| 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. |
