Product Details
| Gene ID | 3604 |
| Accession | Q07011 |
| Alternative Name | Tumor necrosis factor receptor superfamily member 9, 41BB, 4-1BB ligand receptor, CDw137, T-cell antigen 4-1BB homolog, T-cell antigen ILA, CD137<br/>Recombinant Human 4-1BB (TNFRSF9) |
| Species | Human |
| Source | E. coli |
| Description | 4-1BB Receptor (CD137) is a member of the TNF receptor superfamily expressed on activated CD4 and CD8 T cells as well as on activated natural killer cells. The binding of 4-1BB Receptor to its TNF family ligand, 4-1BB ligand (4-1BBL) delivers a co-stimulatory signal to resting T cells leading to high level IL2 production independently of CD28 signaling. Recombinant Human 4-1BB Receptor represents the soluble, cysteine-rich TNFR-like extracellular domain of 4-1BB Receptor. |
| Accession | Q07011 |
| Functions | The ED50 as determined by dose dependent proliferation of human megakaryocytic leukemia cell line is <0.5ng/ml. |
| Formulation | Lyophilized from 0.2 ?m filtered solution in PBS (pH 7.5) |
| Solubility | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Appearance | Lyophilized Powder |
| Molecular Weight | 18 |
| Purity | >95% as determined by SDS-PAGE |
| Concentration | < 1.0 EU/μg of recombinant protein as determined by the LAL method. |
| Shipping Condition | Ambient Temperature |
| Storage Condition | The lyophilized protein is stable for at least one year from date of receipt at -70?C. Upon reconstitution, this cytokine can be stored in working aliquots at 2? – 8?C for one month, or at -20?C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. |
