> 95 % as determined by reducing SDS-PAGE.
|
| 内毒素 |
< 0.1 EU per μg of the protein as determined by the LAL method.
|
| 保存条件 |
Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.
|
| 运输条件 |
This product is provided as lyophilized powder which is shipped with ice packs.
|
| 制剂 |
Lyophilized from sterile PBS, pH 7.4.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual. |

| 背景 |
Tumor necrosis factor ligand superfamily member 9(4-1BBL) is single-pass type II membrane protein which is a member of the the tumor necrosis factor family. 4-1BBL is a 254 amino acids cytokine that is expressed in brain; placenta; lung; skeletal muscle and kidney. TNFSF9 has been shown to reactivate anergic T lymphocytes in addition to promoting T lymphocyte proliferation. This cytokine may have a role in activation-induced cell death (AICD) and cognate interactions between T-cells and B-cells/macrophages. It has also been shown to be required for the optimal CD8 responses in CD8 T cells; and is thought to be involved in T cell-tumor cell interaction.
