Immunohistochemistry using Rockland's polyclonal TNFa antibody showing 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 4°C.  HRP-conjugated goat anti-rabbit antibody was used as the secondary antibody.

TNF alpha Antibody Description

Background
Anti TNF alpha Antibody recognizes TNF alpha (TNF, cachexin, cachectin, tumor necrosis factor-alpha or TNF-a) a cytokine involved in systemic inflammation. TNF alpha is a member of a group of cytokines that stimulate the acute phase reaction. It is produced chiefly by activated macrophages, although it can be produced by other cell types as well. The primary role of TNF alpha is in the regulation of immune cells. TNFis an endogenous pyrogen that is able to induce fever, apoptotic cell death, sepsis (through IL-1 & IL-6 production), cachexia, inflammation, and to inhibit tumorigenesis and viral replication. Dysregulation of TNF production has been implicated in a variety of human diseases, including Alzheimer's disease, cancer, major depression, and inflammatory bowel disease (IBD).
Immunogen
TNF alpha antibody used to produce this IgG fraction antibody was prepared by repeated immunizations with recombinant human TNFa.
Immunogen Type
Recombinant Protein
Storage Condition
Store anti-TNF alpha at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
Application Note
This IgG fraction antibody of anti-Human TNFa has been tested for use in neutralizations, ELISA, immunohistochemistry and immunoblotting.  It recognizes the 17,000 MW TNFa.  Reactivity in other immunoassays is unknown.
Purity/Specifity
This antibody is primarily directed against mature 17,000 MW human TNFa and is useful in determining its presence in various assays.  In general, this antibody also detects primate TNFa in the same formats using similar dilutions.  The antibody does not recognize human TNGß (lymphotoxin).   This IgG fraction antibody will recognize the cell-bound precursor of TNFa as a 26,000 protein in immunoblots, particularly in denatured samples.  This antibody is also useful for neutralization of human and primate TNFa activity in bioassays.  It does not neutralize the biological activity of lymphotoxin. For neutralization, it is recommended to incubate the sample with a 1:200 dilution of the antibody for at least 4 hours before being tested.  A control of similarly diluted normal rabbit IgG is recommended.
