Abstract:
Transcription factors (TFs) play central roles in the regulation of gene expression through binding to specific DNA sequences, and may influence multiple transcription-associated cellular processes including cell development, differentiation, and growth. Alterations in TF levels may lead to a variety of human diseases. Consequently, rapid and sensitive detection of TFs is crucial to both biological research and clinical diagnostics. However, conventional methods for TF assays are usually laborious and time-consuming with poor sensitivity, and sometimes involve the radioactive materials. To overcome these limitations, some new approaches have been developed with a low detection limit, high specificity, high throughput, and low cost. In this paper, we review the recent advances in TF assays and highlight the emerging trends as well.

Chromatin Immunoprecipitation- ChIP
Types of ChIP
ChIP can be divided into two types - X-ChIP and N-ChIP. X-ChIP involves in vivo cross-linking of histones and regulatory proteins to DNA, fragmenting the DNA by sonication, and isolating the protein-DNA...

Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
