General description

Rabbit polyclonal antibody purified by ammonium sulfate precipitation. Recognizes recombinant and monocyte-derived TNF-α.
Recognizes recombinant and monocyte-derived TNF-α. Exhibits some cross-reactivity with lymphotoxin (TNF-β) and mouse TNF-α in L929 cells.
This Anti-TNF-α Rabbit pAb is validated for use in ELISA, Frozen Sections, Immunoblotting, Neutralization Studies, Paraffin Sections, Radioimmunoassay for the detection of TNF-α.

Immunogen

recombinant, human TNF-α

Application

ELISA (see comments)

Frozen Sections (see comments)

Immunoblotting (see comments)

Neutralization Studies (see comments)

Paraffin Sections (see comments)

Radioimmunoassay (see comments)

Packaging

Please refer to vial label for lot-specific concentration.

Warning

Toxicity: Standard Handling (A)

Unit Definition

1 EU corresponds to 0.1 ng endotoxin (EC-6/USP Standard)

Analysis Note

Positive Control
L929 cells

Other Notes

Reacts specifically with natural and recombinant human TNF-α. An approximately 20 µg/ml solution of this antibody has been shown to neutralize 100% of the activity of 0.5 ng/ml recombinant human TNF-α, as measured in the standard L929 cell bioassay. This antibody has also been reported to work for ELISA, frozen sections, immunoblotting, paraffin sections, radioimmunoassay. Endotoxin: ≤5 EU/mg protein as determined by the Biowhittaker Endotect LAL assay. Variables associated with assay conditions will dictate the proper working dilution.
