Gene expression is regulated by different mechanisms. One of them is the binding of Transcription Factors (TF) to DNA sequences.
Traditionally, the study of TF-DNA interactions is made by several time-consuming and cumbersome: Electrophoretic Mobility Shift Assays (EMSA), Chromatin Immunoprecipitation, Western blotting, and expression of fused target and reporter genes.
ELISA-based formats now allow to have a more precise TF-DNA interaction study in addition to an ease of use.
These new tools significantly reduce the necessary runtime (within one day) and eliminate the need for harmful radioactive labeling. High sensitivity and signal-to-noise ratio are also guaranteed.
The TFact™ product-line belongs to these new ELISA-based Transcription Factor DNA binding assays. These indirect ELISAs allow an easy the detection and qualitative determination of the effects of phosphorylation on transcription factor activation profiles in a variety of nuclear and cell lysates from human, mouse and rat.
TFACT™ DNA-BINDING ELISA Kits are available for various Transcription Factors and well-defined phosphorylated sequences: AML1, Jun, Androgen & Estogen Receptors, ATF2, CREB, FOXO, NFkB, STAT, p53, myb, SMAD, Sox …
