	Western Blot: TNF-alpha Antibody [NB600-587] - Analysis using Azide/BSA FREE version of NB600-587. Membrane blocked in 1% BSA-TBS-T 30 min RT, 1:1000 dilution in 1% BSA-TBS-T 4C.
	Immunohistochemistry-Paraffin: TNF-alpha Antibody [NB600-587] - Analysis using Azide/BSA FREE version of NB600-587. Staining of human colon diluted 1:100 and incubated with the sample for 2 hours at 20C. Alexa Fluor(R) 680 goat polyclonal secondary antibody was used diluted 1:5000.
	Immunohistochemistry: TNF-alpha Antibody [NB600-587] - Staining of formalin/PFA-fixed paraffin-embedded sections of human artery tissue sections. Sections were fixed in formaldehyde and subjected to heat mediated antigen retrieval in citrate buffer (pH 6.0). Slides were blocked for ten minutes with 1.5% serum. Primary antibody was diluted 1:100 and incubated with samples for 24 hours at 4C. HRP-conjugated goat anti-rabbit antibody was used as the secondary antibody.

Background

Tumor Necrosis Factor Alpha (TNF alpha) is a protein secreted by lipopolysaccharide stimulated macrophages, and causes tumor necrosis when injected into tumour bearing mice. TNF alpha is believed to mediate pathogenic shock and tissue injury associated with endotoxemia. TNF alpha exists as a multimer of two, three, or five noncovalently linked units, but shows a single 17 kDa band following SDS PAGE under non reducing conditions. TNF alpha is closely related to the 25 kDa protein Tumour Necrosis Factor beta (lymphotoxin), sharing the same receptors and cellular actions. TNF alpha causes cytolysis or cytostasis of certain transformed cells, being synergistic with interferon gamma in its cytotoxicity. Although it has little effect on many cultured normal human cells, TNF alpha appears to be directly toxic to vascular endothelial cells. Other actions of TNF alpha include stimulating growth of human fibroblasts and other cell lines, activating polymorphonuclear neutrophils and osteoclasts, and induction of interleukin 1, prostaglandin E2 and collagenase production. TNF alpha is currently being evaluated in treatment of certain cancers and AIDS Related Complex.
