The decades following the 1950s have produced several such significant advances, as a result of a convergence of developments in molecular biology and in solid state-based electronics instrumentation. Since one of these areas of significant advancement, analytical ultracentrifu gation, has been undergoing a renaissance, we thought it would be a useful activity to call upon a group of researchers who have been developing either the experi mental or theoretical aspects of the methodology and gather in one place a group of articles summarizing the current status of the field. The success of recombinant DNA methodologies at producing biologically active macromolecules of commer cial interest has evoked interests in mechanisms of function. Pursuit of the related questions has emphasized the importance of studies of macromolecular binding and interaction. Several contributions to this volume remind us that analytical ultra centrifugation is rigorously based on solid thermodynamic theory and, as such, is fully capable of providing comprehensive quantitative descriptions of molecular interactions in solution. Furthermore, a number of the chapters provide examples, along with innovative methods for carrying out these characterizations. The past decade has seen several developments that reflect the rebirth of interest in analytical ultracentrifugation. One of these is the commercial development and availability of a new generation of instrumentation for analytical ultracentrifu gation. Other important developments have been the establishment of National Analytical Ultracentrifugation Facilities Laboratories in the u.S. (Storrs, CT) and u.K. (Leicester). A review of the chapter titles in this volume reveals that considerable effort has been devoted to developing computer assisted protocols for data analysis and interpretation. These approaches are both timely and necessary as researchers turn their attention to increasingly complex interacting and self associating systems. Examples are provided in the articles by Harding; Hensley, et al.; Cann; Shire; Philo; and by Holzman and Snyder. x Preface One can expect the future to bring more examples from biotechnology and pharmaceutical laboratories as the chapters by Philo, Shire, Hensley and Holzman clearly presage. An overview of this volume also reveals that the rebirth of interest in Analyti cal Ultracentrifugation will certainly call for a new generation of trained practi tioners. With this potential teaching requirement in mind we have attempted to include chapters that will have didactic as well as expository value to students and trainees as well as to advanced researchers. It should be noted that fully half of the number of authors of this volume had not completed their graduate training at the time of publication of Professor Fujita's classic monograph, "Foundations of Ultracentrifugation Analysis." These statistics reflect a continuation of a scientific tradition extending back more than 50 years to the pioneering developments of The Svedberg. The new computer controlled commercial analytical ultracentri fuge greatly simplifies the execution of experiments and the acquisition of data. Several of the chapters in this volume summarize novel approaches to the subse quent steps in ultracentrifuge investigation, data reduction, analysis and interpreta tion. The developments in Sedimentation Velocity analysis reported by Philo and by Stafford are particularly surprising since this oldest of Sedimentation method ologies was long thought to be of limited value for analysis of complex systems. But the ready availability of high speed and high capacity desk-top computers has made it possible to bring a new level of sophistication and rigor to the analysis of sedimenting boundaries. We look forward to these methods making Sedimenta tion Velocity a workhorse methodology of Modem Analytical Ultracentrifuga tion. We wish to acknowledge the long term support for biological instrumentation and methodology development provided by the Biophysics and the Instrumenta tion Programs of the U.S. National Science Foundation.
