| 货号: 11283 |
| 产品全名: 人 B7-1 蛋白 |
| 规格: 10/50/100 µg |
| 基因符号 CD80;7;7-1;7.1;B1;D28LG;D28LG1;AB7 |
| 目标蛋白: B7-1 |
| UNIPROT ID: P33681 |
| 描述: Recombinant human B7-1 protein with C-terminal human Fc tag |
| 背景: 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. |
| 物种/宿主: HEK293 |
| 分子量: The protein has a predicted molecular mass of 50.0 kDa after removal of the signal peptide. |
| 分子特征: B7-1(Val35-Asn242) hFc(Glu99-Ala330) |
| 纯化: 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. |
| 储存和运输: 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. |
