Product Overview
This rabbit polyclonal antibody targets tumor necrosis factor (gene Tnf) in mouse and rat samples and is validated for Western blot and ELISA. The predicted molecular weight is 25.9 kDa, and the supplier reports an observed band at about 17 kDa.
Tumor necrosis factor (TNF, TNF-α) is a pro-inflammatory cytokine produced mainly by activated macrophages and T cells. Acting through the receptors TNFR1 and TNFR2, it activates NF-κB and MAP kinase pathways and can trigger apoptosis or necroptosis, driving fever and inflammation. TNF is a central target in rheumatoid arthritis and inflammatory bowel disease research and a standard readout in immunology studies.

Samples with a confirmed band (WB): recombinant mouse TNF alpha protein, recombinant rat TNF alpha protein.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 12% SDS-PAGE, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant mouse TNF alpha/Tnf fragment (Asp89–Glu185), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt places tumor necrosis factor in the cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
