Validation Data Gallery

• 

  WB analysis using 26405-1-AP

  PMA, LPS, and Brefeldin A treated THP-1 cells were subjected to SDS PAGE followed by western blot with 26405-1-AP (TNF Alpha antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours. The membrane was stripped and reblotted with GAPDH Monoclonal antibody 60004-1-Ig as loading control.

• 

  WB analysis using 26405-1-AP

  Untreated THP-1 and THP-1 (treated with 80nM PMA overnight, replaced the culture medium with 100 ng/ml LPS for 6 hours with addition of 300ng/ml Brefeldin A for the last 3 hours) cells were subjected to SDS PAGE followed by western blot with 26405-1-AP (TNF alpha antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours.

  IHC staining of human ovary tumor using 26405-1-AP

  Immunohistochemical analysis of paraffin-embedded human ovary tumor tissue slide using 26405-1-AP (TNF Alpha antibody) at dilution of 1:200 (under 10x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0).

• 

  IHC staining of human tonsillitis using 26405-1-AP

  Immunohistochemical analysis of paraffin-embedded human tonsillitis tissue slide using 26405-1-AP (TNF Alpha antibody) at dilution of 1:1000 (under 20x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0).

Tested Applications

• Positive WB detected in: PMA, LPS and Brefeldin A treated THP-1 cells
• Positive IHC detected in: human ovary tumor tissue, human tonsillitis tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:500-1:2000
• Immunohistochemistry (IHC): IHC : 1:50-1:500

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

TNF, as also known as TNF-alpha, or cachectin, is a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. It is expressed as a 26 kDa membrane bound protein and is then cleaved by TNF-alpha converting enzyme (TACE) to release the soluble 17 kDa monomer, which forms homotrimers in circulation. It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. It can bind to, and thus functions through its receptors TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. This cytokine is involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. This cytokine has been implicated in a variety of diseases, including autoimmune diseases, ins resistance, and cancer.
