Description

abm | Recombinant Mouse TNF | Z200219

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.

Functions:

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.

Mouse

Source:

E. coli

Alias:

TNF-alpha, TNF-a, Tumor necrosis factor ligand superfamily member 2, Cachectin, Tnfa, Tnfsf2, Tnf
Recombinant Mouse Tumor Necrosis Factor Alpha (TNF)

Gene Symbol:

TNF

Gene ID:

21926

Accession:

P06804

Formulation:

Recombinant mouse TNF alpha was lyophilized from 0.2 μm filtered PBS solution, pH 7.0.

Solubility:

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.

Appearance:

Lyophilized Powder

Molecular Weight (kDa):

17

Molecular Weight 2 (kDA):

N/A

Molecular Weight 3 (kDA):

N/A

Purity:

>95% as determined by SDS-PAGE

Concentration:

<1.0 EU/μg of recombinant protein as determined by the LAL method.

Shipping Condition :

Ambient Temperature

Storage Condition:

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.
