Assays for transcription factor activity

Douglas Browning, N Savery, A Kolb, Stephen Busby

Research output: Chapter in Book/Report/Conference proceedingChapter


Transcription factors interact at promoters to modulate the transcription of genes. This chapter describes three in vitro methods that can be used to monitor their activity: transcript assays, abortive initiation assays, and potassium permanganate footprinting. These techniques have been developed using bacterial systems, and can be used to study the kinetics of transcription initiation, and hence to unravel regulatory mechanisms.
