Centrifugal Separations in Molecular and Cell Biology focuses on the application of modern centrifugation technology in molecular and cell biology, including the separation and fractionation of biological particles by centrifugation on the preparative and analytical scales. The selection first covers the principles and practices of centrifugation and the bases of centrifugal separations. Discussions focus on the basic concepts of sedimentation theory, centrifugation methods, designing centrifugation experiments, care of centrifuges and rotors, and statistical estimation of molecular parameters. The book also ponders on the practical aspects of rate-zonal centrifugation, including gradient materials, density and viscosity of glycerol solutions, and resolution and gradient shape. The publication examines fractionations in zonal rotors and the quantitative aspects of rate-zonal centrifugation. The text then reviews isopycnic centrifugation in ionic media and analytical centrifugation. Topics include separation by isopycnic banding, large-scale preparative procedures, and density-gradient solutes. The selection is a valuable reference for readers interested in centrifugation technology.

New edition of biochemistry textbook which introduces principles and techniques used in undergraduate practical classes.

Molecular Biology or Molecular Genetics - Biology Department Biochemical Genetics - Biology or Biochemistry Department Microbial Genetics - Genetics Department The book is typically used in a one-semester course that may be taught in the fall or the spring. However, the book contains sufficient information so that it could be used for a full year course. It is appropriate for juniors and seniors or first year graduate students.

Centrifugation in Density Gradients provides information pertinent to the fundamental aspects of density gradient centrifugation. This book discusses the benefits of density gradient centrifugation to membrane-bound particles. Organized into nine chapters, this book begins with an overview of the method of differential or fractional centrifugation. This text then explores the physical basis of density gradient centrifugation. Other chapters deal with the nuts and bolts of density gradient centrifugation, the construction and composition of gradients, the properties and operation of centrifuge systems, and certain arcane but highly useful procedures. This book discusses as well density gradient centrifugation in the analytical ultracentrifuge. The final chapter deals with a collection of protocols for separating particles ranging in size from whole cells to macromolecules. This book is intended to be suitable for readers who need to separate biological particles. Biologists, chemists, biochemists, cytologists, physiologists, scientists, and research workers will also find this book useful.

Biological and medical research relies upon an integrated understanding of the molecules within cells and of the interactions between cells. This has imposed great demands on investigators. Being an expert in a relatively narrow area is no longer sufficient as many studies now require the use of a wide range of techniques to provide the necessary integration. A lack of familiarity with the experimental possibilities can make such diversification difficult to achieve. This two volume set of Essential Cell Biology is designed to help researchers overcome these problems. It has not been possible to include all of the techniques available in cell biology so the challenge was to identify those that might be most relevant to researchers who are new to this topic. We have tried to cover both traditional and more recent approaches. The theory and basic principles of each technique are described, together with detailed protocols and advice for trouble shooting. Directions to more specialised techniques are also included. We hope the result inspires readers to experience the challenges and rewards of cell biology research for themselves and to contribute to the ongoing task of understanding the life of the cell. Essential Cell Biology volume 1 focuses on techniques for studying cell structure whilst volume 2 concentrates on understanding how the cell functions. Volume 1 details the essential background information and protocols for observing and understanding cell morphology and cell structure, including, for example, investigations of nucleic acids, lipids, and the cytoskeleton. This is the essential guide to cell biology for researchers new to the field.
