TNF alpha Antibody Description

Tumor necrosis factor-alpha (TNFa) in humans is a pleiotropic inflammatory cytokine. It is expressed by many different stimulated cell types including monocytes, endothelial cells, fibroblasts and both T and B-lymphocytes, but especially by macrophages. It affects most organs. The production of TNFa is induced by IL-1, PDGF, IFN-beta, NGF, Oncostatin M and certain fungal, viral, and parasitic invasions. Bacterial lipopolysaccharide is an especially potent stimulus. The primary role of TNFa is in the regulation of immune cells. TNFa mediates septic shock in response to infection. It initiates a cascade of cytokines and increases vascular permeability, thereby recruiting macrophages and neutrophils. TNFa secreted by macrophages causes blood clotting which helps contain infection. TNFa is also able to induce apoptotic cell death or inflammation, and to inhibit viral replication. It possesses growth stimulating, inhibitory, and self regulatory properties. Dysregulation of TNFa production has been implicated in a variety of human diseases, as well as cancer. The presence of TNFa is responsible for diverse immunomodulatory and toxic effects. For instance, TNFa induces neutrophil proliferation during inflammation, but it also induces neutrophil apoptosis upon binding to the TNF-R55 receptor. TNFa causes necrosis of some types of tumors, but promotes growth of other types. Low levels may aid in maintaining homeostasis by regulating the body's circadian rhythm, and may promote remodeling or replacement of injured and senescent tissue by stimulating fibroblast growth. High levels of TNFa correlate with increased risk of mortality.

This protein-A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a recombinant protein raised in yeast, corresponding to 154 amino acids of mature swine TNFa.
Immunogen Type
Recombinant Protein
Storage Condition
Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
Application Note
This protein A purified antibody is suitable for ELISA and Western blotting.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 16.9 kDa in size corresponding to swine TNFa by western blotting in the appropriate cell lysate or extract.
This product was Protein-A purified from monospecific antiserum by chromatography. It is specific for swine TNFa protein. A BLAST analysis was used to suggest cross-reactivity with TNFa from swine sources based on 100% homology with the immunizing sequence. Partial reactivity is expected against TNFa from baboon based on 90% homology. Cross-reactivity with TNFa from sources other than swine has not been determined.
