TNFR2/TNFRSF1B Protein, Human, Recombinant (His Tag): 产品信息

纯度
> 97 % as determined by SDS-PAGE
内毒素
< 1.0 EU per μg of the protein as determined by the LAL method
生物活性
1. Measured by its ability to inhibit TNF-α mediated cytotoxicity in L-929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 0.2-0.8 μg/ml in the presence of 0.25 ng/mL recombinant human TNF-α.
2. Measured by its binding ability in a functional ELISA. Immobilized TNFRII-His (Cat:10417-H08H) at 10 μg/mL (100 μL/well) can bind TNFα/Biotin (Cat:10602-HNAE), the EC50 of TNFα/Biotin (Cat:10602-HNAE) is 20-60 ng/mL.
蛋白构建
A DNA sequence encoding the extracellular domain (Met 1-Asp 257) of human TNFRII (NP_001057.1) was expressed, fused with a C-terminal polyhistidine tag.
NP No.

分子量
The recombinant human TNFRII comprises 246 amino acids and has a calculated molecular mass of 26.7 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh TNFRII is approximately 42-45 kDa due to glycosylation.
缓冲液
Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

TNFR2/TNFRSF1B 背景信息

Tumor necrosis factor receptor superfamily, member 1B (TNFRSF1B), also known as Tumor necrosis factor receptor 2 (TNFR2) or CD12b antigen, is a member of the tumor necrosis factor receptor superfamily. TNFR2/CD12b/TNFRSF1B is a member of the TNF-receptor superfamily. This protein and TNF-receptor 1 form a heterocomplex that mediates the recruitment of two anti-apoptotic proteins, c-IAP1 and c-IAP2, which possess E3 ubiquitin ligase activity. Knockout studies in mice also suggest a role of this protein in protecting neurons from apoptosis by stimulating antioxidative pathways. TNFR2/CD12b/TNFRSF1B is not a major contributing factor to the genetic risk of type 2 diabetes, its associated peripheral neuropathy and hypertension and related metabolic traits in North Indians. Tumor necrosis factor receptor superfamily, member 1B (TNFRSF1B) has been reported to be associated with SLE risk in Japanese populations. TNFR2/CD12b/TNFRSF1B serves as a receptor with high affinity for TNFSF2 and approximately 5-fold lower affinity for homotrimeric TNFSF1. This receptor mediates most of the metabolic effects of TNF-alpha. Isoform 2 blocks TNF-alpha-induced apoptosis, which suggests that it regulates TNF-alpha function by antagonizing its biological activity.
