| 来源 | The recombinant Human CD8 alpha&beta Heterodimer Protein, (amino acids Ser22-Asp182(CD8 alpha) acidic tail & Leu22-Pro170(CD8 beta) basic tail) fused with a His-Flag tag at the C-terminus, was produced in HEK 293 cells. |
| 产品标签 | C-His-Flag |
| 生物素化 | no |
| 确定序列 | Ser22-Asp182(CD8 alpha) acidic tail & Leu22-Pro170(CD8 beta) basic tail |
| 分子量 | The recombinant Human CD8 alpha&beta Heterodimer protein with the His-Flag tag at the C-terminus has a predicted MW of 23.54 kDa (CD8 alpha) and 22.62 kDa (CD8 beta). Due to glycosylation, the protein migrates to 26-28 kDa (CD8 alpha) and 28-32 kDa (CD8 beta) based on Tris-Bis PAGE result. |
| 活性 | Immobilized recombinant Human CD8A&CD8B protein with the C-His-Flag tag at 0.5 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Anti-CD8 Antibody protein with the C-hFc tag with the EC50 of 15.2 ng/ml determined by ELISA. |
| Form | Lyophilized |
| 形式 | Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| 制剂 | It is recommended to reconstitute the lyophilized recombinant Human CD8 alpha&beta Heterodimer Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening. |
| 纯度 | >95% by SEC-HPLC and SDS-PAGE under reducing conditions. |
| 内毒素 | Less than 1 EU per ug of protein as determined by LAL method. |
| 运输 | The recombinant Human CD8 alpha&beta Heterodimer Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below. |
| 稳定性与储存 | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70°C as supplied. 1 week, 2 to 8°C under sterile conditions after reconstitution. 6 months, -20 to -70°C under sterile conditions after reconstitution. |
| 注意事项 | Conditions of optimal recombinant Human CD8 alpha&beta Heterodimer Protein performance should be determined experimentally by the investigator. |

文献
BP003294: Human CD8 alpha&beta Heterodimer Protein with the C-His-Flag Tag (人 CD8 α 和 β 异二聚体蛋白 C-His-Flag 标签)
CD8 alpha&beta (CD8αβ) is a heterodimeric form of CD8. CD8α is required for surface expression of CD8β. The extracellular IgV-like domain of CD8α interacts with the α3 portion of the class I MHC molecule. CD8αβ is expressed on human peripheral T cells and functions as a coreceptor and can greatly increase the sensitivity and breadth of antigen recognition by CD8+ peripheral T cells bearing TCR.
