This purified ABfinity™ recombinant rabbit monoclonal antibody recognizes TNF-alpha in human samples.

ABfinity™ antibody characteristics include:

• Validation in Western blot and indirect ELISA
• Superior lot-to-lot consistency
• Extremely high specificity and sensitivity
• Recombinant rabbit monoclonal antibody
• Specific for TNF-alpha

Tumor necrosis factor-alpha (TNF-A) is a pleiotropic inflammatory cytokine that stimulates acute phase reaction. The primary role of TNF is in the regulation of immune cells. Other beneficial functions of TNF-A include its role in the immune response to bacterial and certain fungal, viral, and parasitic invasions, as well as its role in the necrosis of specific tumors. TNF-A is a trimeric protein encoded within the major histocompatibility complex.

Exceptional Consistency Saves You Time and Money
ABfinity™ antibodies are produced by transfection of mammalian cells with heavy and light chain antibody cDNAs. This provides you with the highest consistency between lots, eliminating the need to revalidate your assays for each lot.

High Specificity Means More Reliable Data
The proprietary recombinant technology employed in the production of ABfinity™ antibodies means you are assured of the greatest degree of reliability. Staining of nonspecific proteins is virtually eliminated while very high sensitivity is achieved. Invitrogen has validated this antibody in Western blotting.

High Sensitivity Lets You Detect Low Levels of Target Protein
ABfinity™ antibodies demonstrate much higher sensitivity than ordinary antibodies. Proteins expressed in low levels can be detected with high specificity allowing you to use less of your precious samples than with ordinary antibodies.

Recombinant Rabbit IgG—Use Like Any Other IgG Antibody
As with traditional IgG antibodies, gel electrophoresis of ABfinity™ antibodies produces a 150 kDa band under non-reducing conditions and 50 kDa and 25 kDa bands under reducing conditions.
