Description	Tumor Necrosis Factor 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.
Alternative Names	Cachectin ; TNF ; Tumor necrosis factor ligand superfamily member 2 ; TNF-a ; Tumor necrosis factor
Quantity	50 µg
Regulatory	RUO
Source	CHO cells
Host	Human
Endotoxin Level	<1.0 EU/μg of recombinant protein as determined by the LAL method.
Biological Activity Comment	The ED(50) was determined cytolysis of murine L929 cells in the presence of Actinomycin D is ≤ 0.02 ng/mL, corresponding to a specific activity of > 5.0 x 10^7 units/mg.

Weight	18.0 kDa

Description	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.
Format	Lyophilized Powder TNF-a was lyophilized from a 0.2μm filtered concentrated (1.0 mg/mL) solution in PBS, pH 7.2.
Purity	>95% as determined by SDS-PAGE
Storage	The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
