In this special Methods collection on DNA helicases, I have solicited articles from leading experts in the field with a priority to gather a defined series of papers on highly relevant topics that encompass biological, biochemical, and biophysical aspects of helicase function. The experimental approaches described provide an opportunity for both new and more experienced scientists to use the information for the design of their own investigations. The reader will find detailed methods for single-molecule studies, novel biochemical experiments, genetic analyses, and cell biological assays in a variety of systems with an emphasis placed on state-of-the-art techniques to measure helicase function. Contributing authors were strongly encouraged to provide a carefully constructed description of the methods employed so that others might use this information in a manner that will be useful for their own particular application and helicase of interest. This special issue of Methods dedicated to DNA helicases offers readers a treasure chest of unique experimental approaches and protocols focused on rapidly developing techniques that are useful for studying both in vivo and in vitro aspects of helicase function.
