- HOST SPECIES: Rabbit
- SPECIES REACTIVITY: Human
- IMMUNOGEN: Produced from sera of rabbits pre-immunized with highly pure (>98%) recombinant hTNF-alpha (human Tumor Necrosis Factor-alpha).
- CONJUGATE: Unconjugated
- TESTED APPLICATIONS: ELISA, Neutralization Assay, WB
- APPLICATION NOTE: Neutralization:
To yield one-half maximal inhibition [ND50] of the biological activity of hTNF-α (0.25 ng/mL), a concentration of 0.012 - 0.014 μg/mL of this antibody is required.
ELISA:
To detect hTNF-α by direct ELISA (using 100 μL/well antibody solution) a concentration of at least 0.5 μg/mL of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of 0.2 - 0.4 ng/well of recombinant hTNF-α.
Sandwich:
To detect hTNF-α by sandwich ELISA (using 100 μL/well antibody solution) a concentration of 0.5 - 2.0 μg/mL of this antibody is required. This antigen affinity purified antibody, in conjunction with our Biotinylated Anti-Human TNF-α (XP-5282Bt) as a detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant hTNF-α.
Western Blot:
To detect hTNF-α by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 μg/mL. Used in conjunction with compatible secondary reagents the detection limit for recombinant hTNF-α is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
Properties
- PURIFICATION: Anti-hTNF-alpha specific antibody was purified by affinity chromatography employing immobilized hTNF-alpha matrix.
- CLONALITY: Polyclonal
- PHYSICAL STATE: Lyophilized
- CONCENTRATION: batch dependent
- STORAGE CONDITIONS: TNF-a antibody is stable for at least 2 years from date of receipt at -20°C. The reconstituted antibody is stable for at least two weeks at 2-8°C. Frozen aliquots are stable for at least 6 months when stored at -20°C. Avoid repeated freeze-thaw cycles.

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.
