Footprinting of Nucleic Acid-Protein Complexes

Footprinting of Nucleic Acid-Protein Complexes provides protocols for studying the stoichiometry, binding site size and location, and structural changes in nucleic acids caused by their interaction with proteins. The methods are central to studying key biological processes, such as transcription and translation. The techniques are important to experiments in vivoand in vitro, in eukaryotes and in prokaryotes, at qualitative and quantitative levels,and across many disciplines.This book is a laboratory manual of footprinting techniques for studying nucleic acid-protein interactions. It contains clear and concise descriptions of the most important methodologies, and includes in vivo as well as in vitro applications. It is aimed at bench scientists from graduate students on, and should be of value in industrial labs as well as in academic settings. Use of different footprinting approaches can provide unique insights into DNA-protein systems. The protocols containedin this handbook are written to be"user-friendly,"and thus should be conducive to extending the use of footprinting to new systems. The section on quantitative analysis of DNAse I footprints should prove especially useful for in depth evaluation of cooperative interactions.
