TNFRSF1A Protein, Human, Recombinant (His & Fc Tag): Product Information

Purity
> 90 % as determined by SDS-PAGE
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Activity
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 2-12ng/mL in the presence of 1 ng/mL recombinant human TNF-α.
Protein Construction
A DNA sequence encoding the human TNFRI (NP_001056.1) extracellular domain (Met 1-Thr 211) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
Accession#
Expressed Host
HEK293 Cells
Species
Human
Predicted N Terminal
Ile 22
Molecule Mass
The recombinant human TNFRI/Fc is a disulfide-linked homodimer. The reduced monomer consists of 438 amino acids and has a predicted molecular mass of 49.3 kDa. As a result of glycosylation, rh TNFRI/Fc monomer migrates with an apparent molecular mass of 60-65 kDa in SDS-PAGE under reducing conditions.
Formulation
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Please refer to the specific buffer information in the hard copy of CoA.
Shipping
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.
Stability & Storage
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.
Reconstitution
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

TNFRSF1A Background Information

The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 32 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. CD12a (cluste of differentiation 12a), also known as TNFR1 / TNFRSF1A, is a member of CD family, tumor necrosis factor receptor superfamily. CD12a is one of the most primary receptors for the tumor necrosis factor-alpha. It has been shown to be localized to both plasma membrane lipid rafts and the trans golgi complex with the help of the death domain (DD). CD12a can activate the transcription factor NF-κB, mediate apoptosis, and regulate inflammation processes.
