A number of the methods described in the volume are unpub- lished and their inclusion indicates the speed at which this field is moving. This volume is not a review but each chapter contains methods validated by the experts who have spent time in developing the protocols. The hallmark of this series is the comprehensive way in which the meth- ods are described, which includes a list of all the reagents needed for each protocol. Of importance is the section on tips and pitfalls that the authors have discovered while developing their protocols. The manual itself is designed to be used by researchers in universities and industry who are familiar with a range of biological techniques but who want to set up quickly a novel assay system. We encourage a dialog between readers and authors, which may also result in useful collaborations. The first chapter gives an overview of the change in methodologies that have been used for discovering active compounds. Safety considerations have also been reviewed because there are some significant differences in contain- ment requirements between the United States and the United Kingdom, for example. Routine quality testing of cell cultures has also been highlighted because there are many stories of results being invalidated when target cells have been contaminated by micro-organisms, which, even at low levels, may significantly alter antiviral endpoints. For each virus group the chapters that describe the assays start with cell- based systems and progress through to those of biochemical and molecular design. Those associated with hepatitis viruses predominantly describe proto- cols for HBV, but a relatively new method is described for a high throughput screen for compounds against HVC. In the herpesvirus section, cell-based assays are described for HSV 1 and 2, CMV, VZV, and EBV. A chapter details the methodology for monitoring drug resistance in clinical herpesvi- ruses, which is now mandatory in immunocompromised patients. The section on HIV methods contains a wide variety of methods ranging from those evalu- ating the activity of topical virucidal agents, an area that may prove to be v vi Preface important in reducing the rates of infection, through cell-based assays and molecular techniques used in identifying agents active against reverse tran- scriptase, protease, and integrase. Of importance is the chapter describing the methods that identify the phenotypic and genotypic properties of resistant clini- cal isolates. This methodology undoubtedly will become more automated, but in nondiagnostic settings it will be necessary to carry out such studies on a small scale. The two assays on human papillomaviruses describe a relatively simple method for identifying E6 and E7 proteins, responsible for cellular immortalization, in cell lysates and a molecular approach for identifying the E1 and E2 proteins by in vitro translation. Finally, some chapters describe the virological and biochemical assays that measure the resistance of viruses against one of the new generations of neuraminidase inhibitors. Production of volumes such as this are always flawed by the passage of time. However, we hope that it will provide a snapshot of the valuable and exciting work that continues in this area of science and be a significant aid to those involved in discovering new compounds.
