Recombinant Human TNF RII (C-F

Recombinant Human TNF RII (C-Fc) (CP11)

产品说明(Description)

Recombinant Human Tumor Necrosis Factor Receptor II is produced by our Mammalian expression system and the target gene encoding Leu23-Asp257 is expressed with a Fc tag at the C-terminus. 

Accession #: P20333

Known as: TNF-RII; TNFRII; TNF RII; Tumor necrosis factor receptor superfamily member 1B; TNFRSF1B; Tumor necrosis factor receptor 2; TNF-R2; Tumor necrosis factor receptor type II; p75; p80 TNF-alpha receptor; CD120b

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.

 

质量控制(Quality Control) 

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.

Reconstituted protein solution can be stored at 4-7°C for 2-7 days.

Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景(Background)

Tumor necrosis factor receptor superfamily member 1B (TNFRSF1B) is a member of the tumor necrosis factor receptor superfamily. Human TNF RII contains four cysteinerich repeats in its ECD, which shares 58% and 56% amino acid sequence identity with the mouse and rat orthologs, respectively.TNF RII is expressed predominantly on cells of the hematopoietic lineage, such as T and natural killer cells, as well as on endothelial cells, microglia, astrocytes,neurons, oligodendrocytes, cardiac myocytes, thymocytes, and mesenchymal stem cells.TNF RII binds to the membranebound forms of TNFα and Lymphotoxinα/TNFβ soluble TNF is thought to signal predominately through TNF RI.Soluble TNF RII is believed to inhibit TNF biological activity by binding TNF thereby preventing it from activating membrane TNF receptors.
