Transcription factors (TFs) are DNA binding proteins that play essential roles in regulating gene expression. They act as sensors to monitor changes of cells and convert the signals into changes of gene expression. Often, a specific cellular signal pathway can activate multiple TFs and the expression of a specific gene is under the control of multiple TFs.

Signosis provides a variety of tools to meet a variety of needs and facilitate the analysis of transcription factors. The TF Activation Profiling Plate Arrays, Transcriptional Interaction TF Plate Arrays, and Promoter-Binding TF Profiling Array are for the analysis of multiple TFs, and TF Filter Plate Assays, EMSA Kits, Luciferase Reporter Vectors and Vector Sets, Luciferase Stable Cell Lines, TF ELISA, and TF Western Blot Detection Assay Kits can monitor individual TFs.
