NFκB Introduction & Background

Nuclear Factor κB (NFκB) is an important transcription factor complex that plays critical roles in regulating the expression of many genes in cells, including pathways that control the immune response, inflammation, development, cellular growth, and apoptosis. When NFκB is misregulated it can lead to many different disease states, including multiple types of cancer, neurodegenerative diseases, heart diseases, and inflammation. These disorders are usually due to overactive NFκB complexes, which highlights the importance of being able quickly, accurately, and reliably measure its activity in samples.

Using TransAM DNA-Binding ELISAs to Measure NFκB Activity

TransAM NFκB kits are DNA-binding ELISAs that provide everything needed to study NFκB in biological samples, including a positive control extract. These assays are available with antibodies specific for the activated form of p50, p52, and p65. A family kit is also available with the ability to screen the members of the NFκB family (p50, p52, p65, c-Rel, and RelB).
The kit manual and other important documents can be downloaded from the Documents tab below.
Recombinant p50 and Recombinant p65 proteins are available separately to generate an optional protein standard curve in the TransAM NFκB Transcription Factor ELISA kits.
Flow chart of the TransAM DNA-binding transcription factor ELISA


Figure 1. Flow chart of the TransAM process. Activated transcription factor in the cell extract binds to the consensus-binding site on the oligo immobilized in the well. Incubation with the supplied primary and secondary antibodies specifically quantifies the amount of activated transcription factor.

TransAM NF-kB Family Kit Data

TransAM NFκB Assay is More Sensitive than a Gel Shift

TransAM NFkB data vs. gel shift
Figure 2. TransAM NFκB is more sensitive than gelshift. Human fibroblast WI-38 cells are stimulated with IL-1α for 30 minutes. Increasing amounts of whole-cell extract are assayed using (A) the TransAM NFκB p50 Kit or (B) a gel shift assay.


NFκB Family Profiling in Multiple Cell Lines
