3D Structure
ModBase 3D Structure for P06804
E Coli
>97%, as determined by SDS-PAGE and HPLC
Recombinant mouse TNF alpha was lyophilized from 0.2 um filtered PBS solution, pH 7.0.
Host Note
Optimized DNA sequence encoding Mouse Tumor Necrosis Factor-alpha extracellular domain was expressed in Escherichia Coli.
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/ug (1EU/ug).
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.
Molecular Weight Note
Native Mouse Tumor Necrosis Factor-alpha is generated by the proteolytic removal of the signal peptide and propeptide, this molecule has a calculated mass of approximately 17kDa.

Recombinant Mouse TNF is a disulfide-linked monomer protein, consisting of 157 amino acids and migrates as an approximately 17 kDa protein under reducing conditions.
Preparation and Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20 degree C.
Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree - 8 degree C for one month, or at -20 degree C for six months, with a carrier protein without detectable loss of activity.

Avoid repeated freeze/thaw cycles.
Other Notes
Small volumes of TNF recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
TNF recombinant protein
TNF is secreted by macrophages, monocytes, neutrophils, T-cells, NK- cells following their stimulation by bacterial lipopolysaccharides. Cells expressing CD4 secrete TNF- alpha while CD8 (+) cells secrete little or no TNF- alpha. Stimulated peripheral neutrophilic granulocytes but also unstimulated cells and also a number of transformed cell lines, astrocytes, microglial cells, smooth muscle cells, and fibroblasts also secrete TNF. Human milk also contains this factor.

NCBI Summary for TNF
This gene encodes a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. Members of this family are classified based on primary sequence, function, and structure. This protein is synthesized as a type-II transmembrane protein and is reported to be cleaved into products that exert distinct biological functions. It plays an important role in the innate immune response as well as regulating homeostasis but is also implicated in diseases of chronic inflammation. In mouse deficiency of this gene is associated with defects in response to bacterial infection, with defects in forming organized follicular dendritic cell networks and germinal centers, and with a lack of primary B cell follicles. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013]
UniProt Comments for TNF
TNF-a: Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation. Homotrimer. Interacts with SPPL2B. Belongs to the tumor necrosis factor family.
