Synonyms
TNF; N/A; Recombinant Mouse TNF; TNF-alpha; TNF-a; Tumor necrosis factor ligand superfamily member 2; Cachectin; Tnfa; Tnfsf2; Tnf; Recombinant Mouse Tumor Necrosis Factor Alpha (TNF); TNF active protein
Host
E Coli
Purity/Purification
>95% as determined by SDS-PAGE
Form/Format
Lyophilized from 0.2 um filtered PBS solution, pH 7.0.
Sequence Length
219
Bioactivity
The ED(50) was determined cytolysis of murine L929 cells in the presence of Actinomycin D is <= 0.05 ng/mL, corresponding to a specific activity of >= 3.0 x 10^7 units/mg.
Endotoxin Level
<1.0 EU/ug of recombinant protein as determined by the LAL method.
Reconstitution
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.
Preparation and Storage
The lyophilized protein is stable for at least one year from date of receipt at-70 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2-8 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.

Related Product Information for TNF active protein
TNF is secreted by macrophages, monocytes, neutrophils, T cells, natural killer 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. The synthesis of TNF-alpha is induced by many different stimuli including interferons, IL-2, GM-CSF, SP, Bradykinin, immune complexes, inhibitors of cyclooxygenase and PAF (platelet activating factor). Human TNF-alpha is a non-glycosylated protein of 17 kDa and a length of 157 amino acids. Murine TNF-alpha is N-glycosylated. Homology with TNF-beta is approximately 30%. TNF-alpha forms dimers and trimers.

Product Notes
The TNF tnf (Catalog #AAA214321) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "TNF, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
