| 生物活性 |
Measure by its ability to induce IL-8 secretion in HT29 cells. The ED50 for this effect is <2.0 ng/mL. The specific activity of recombinant human IL-1 beta is approximately >3 x 107 IU/mg.
|
| 纯度 |
> 98 % 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 8.0.
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. |
| 复溶方法 |

| 背景 |
IL1B belongs to the IL-1 family. Interleukin 1 (IL-1) is a family of polypeptide cytokines consisting of two agonists, IL-1 alpha (IL-1F1) and IL-1 beta (IL-1F2) encoded by two distinct genes and perform identical biological functions. IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response. It is identified as endogenous pyrogens, and is reported to stimulate the release of prostaglandin and collagenase from synovial cells.
