FKHR (FOXO1) Transcription Factor Info
The Forkhead transcription factor FKHR (also known as FOXO1, or Forkhead in rhabdomyosarcoma) belongs to the FOX family of transcription factors that regulate genes involved with proliferation, differentiation and longevity. While all FOX proteins contain the distinct forkhead-box motif that binds DNA, the proteins can be further grouped into subclasses. Members of FOX class O regulate metabolism, proliferation and longevity as influenced by post-translational modifications such as phosphorylation, acetylation and ubiquitination. TransAM FKHR Kit contains an antibody specific for detection of FOXO1 in human, mouse and rat samples.

The TransAM® transcription factor ELISA advantage
Historically, transcription factor studies have been conducted using gelshift, Western blot and reporter plasmid transfections, which are time-consuming, do not allow for high-throughput and provide only semi-quantitative results. TransAM assays are up to 100 times more sensitive than gelshift techniques, and can be completed in less than 5 hours. Because TransAM is an ELISA-based assay*, there is no radioactivity, and the high-throughput stripwell format enables simultaneous screening of 1-96 samples. Inconsistencies due to variable reporter plasmid transfections are eliminated, along with the need to construct stable cell lines.
Why use TransAM® transcription factor ELISAs?
- Up to 100-fold more sensitive than gelshift assays
- Eliminates the use of radioactivity and the need to run gels
- Results in less than five hours
- Colorimetric readout enables easy, quantitative analysis with spectrophotometry at 450 nm
- 96-stripwell format enables both high and low throughput
How TransAM® transcription factor ELISAs work
The TransAM format is perfect for assaying transcription factor binding to a consensus-binding site. TransAM Kits contain a 96-stripwell plate to which the consensus-binding site oligo has been immobilized. Activated nuclear extract is added to each well and the transcription factor of interest binds specifically to this bound oligonucleotide. A primary antibody specific for an epitope on the bound and active form of the transcription factor is then added followed by subsequent incubation with secondary antibody and Developing Solution to provide an easily quantified, sensitive colorimetric readout (Figure 1).
