| Overview |
TNF-α stands for tumor necrosis factor α, also termed TNFSF2 (TNF ligand superfamily member 2) or Cachectin. Mouse TNF-α is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.
TNF-α can be used for a variety of applications, including:
- Induction of Mo-DC maturation.
- Cytotoxicity and cell proliferation assays.
- Assessment of apoptosis and viral protection.
- Investigation of TNF-α-induced signaling pathways.

Background information
TNF-α is a proinflammatory cytokine that is produced mainly by activated monocytes and macrophages in response to infection, injury, and tumor burden. TNF-α production has also been reported for a variety of other cell types involved in inflammatory responses, including T cells, NK cells, and neutrophils as well as a number of non-immune cells, such as keratinocytes and astrocytes. TNF-α has a broad spectrum of biological activities. In addition to its central role in inflammation, TNF-α is noted for its cytotoxic and tumoricidal abilities either by necrosis or induction of apoptosis. Further functions include antiviral activity, growth modulation, and induction of cellular differentiation. Despite its various beneficial actions, TNF-α also plays a detrimental role in, for example, septic shock syndrome, tissue injury, inflammation, cachexia, and diabetes.
Quality description
Research-grade cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/µg (<1 EU/µg), and purities are >95%. The biological activity is tested in appropriate bioassays. |
