Biological Activity
The ED50 is <30 pg/mL as measured by L-929 mouse fibrosarcoma cells, corresponding to a specific activity of >3.3 × 107 units/mg.

Appearance
Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against PBS.

Endotoxin Level
<0.2 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Human Tumor Necrosis Factor-alpha/TNFSF2 (rHuTNF-α/TNFSF2) to 100 µg/mL using ddH2O or diluted with PBS.

Storage & Stability
Lyophilized recombinant Human Tumor Necrosis Factor-alpha/TNFSF2 (rHuTNF-α/TNFSF2) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
Room temperature in continental US; may vary elsewhere.

Background
Tumor necrosis factor α (TNF-α, also known as cachectin) is a strong pro-inflammatory cytokine playing an important role in the immune system during inflammation, cell proliferation, differentiation and apoptosis. TNF-α is type II transmembrane protein that can be expressed in both membrane-bound and secreted forms. Receptors for TNF-a are part of TNF receptor (TNFR) superfamily, with characteristic intracellular segment, a transmembrane domain, and an extracellular ligand-binding domain. They are type I transmembrane glycoproteins characterized by a cysteinerich motif (up to 40 aminoacids) repeated 2-6 times in the extracellular N-terminal domain[1]. Tumor necrosis factor-α (TNF-α) is a pleiotropic factor exhibiting antitumor effects, alters endothelial barrier function, reduces tumor interstitial pressure and mediates immune responses. TNF-α is associated with a number of cell signalling events, associated with cell necrosis and apoptosis, and is important for resistance to infection and cancer[2]
