The last few years have seen the rapid development of new methodologies in molecular biology. New techniques, particularly in genetic engineering, have been introduced, and the sensitivity of older techniques improved. Volume II in this series extends material covered in volume I. As with the previous volume, the majority of chapters relate to nucleic acid methodology, but immunological methods and protein purification techniques not covered in the first volume are covered in Volume II. Each chapter aims to describe both the theory and relevant practical details for a given technique, identifying its potential and limitations, although the book is not intended as a "recipe" book. It is aimed at senior undergraduates and research workers who are looking for an introductory review of a particular technique. This book should be of interest to senior undergraduates and research workers who are looking for an introductory review of a particular technique.

In recent years there has been a tremendous increase in our understanding of the functioning of the cell at the molecular level. This has been achieved in the main by the invention and development of new methodology, parti- larly in that area generally referred to as "'genetic en- neering". While this revolution has been taking place in the field of nucleic acids research, the protein chemist has at the same time developed fresh methodology to keep pace with the requirements of present day molecular bi- ogy. Today's molecular biologist can no longer be content with being an expert in one particular area alone. He/she needs to be equally competent in the laboratory at h- dling DNA, RNA, and proteins, moving from one area to another as required by the problem he/she is trying to solve. Although many of the new techniques in molecular biology are relatively easy to master, it is often difficult for a researcher to obtain all the relevant information nec- sary for setting up and successfully applying a new te- nique. Information is of course available in the research l- erature, but this often lacks the depth of description that the new user requires. This requirement for in-depth pr- tical details has become apparent by the considerable - mand for places on our Molecular Biology Workshops held at Hatfield each summer.

Animal Cell Culture, the latest volume in Humana's highly successful Methods in Molecular Biology series, provides detailed practical techniques for the culture of a broad spectrum of basic cell cell types. Chapters offer hands-on methods for creating mammalian fibroblastic cell cultures and maintaining culture conditions for epithelial, neuronal, and hematopoietic cells among others. Attention is given to the diversity of culture media and extracellular matrices needed to maintain the differentiated functions of the cultured cells. The book's special strength lies in its descriptions of culture techniques for both living and fixed cells. Chapters cover techniques such as: cinematographic analysis in situ mRNA hybridization immunofluorescence immunoelectron microscopy somatic cell hybridization DNA transformation insect cell culture creation of hybridoma cell lines monoclonal antibody techniques new, specialized methodologies. A useful appendix lists the most commonly used culture media. Comprehensive in scope and coverage, and thoroughly up-to-date, Pollard and Walker's unique handbook on ANIMAL CELL CULTURE is an indispensable resource for both the novice and the seasoned expert.

Plant Cell and Tissue Culture continues the high standards of Humana's Methods in Molecular Biology series. Its step-by-step approach (a hallmark of the series) is applied to a wide range of basic laboratory techniques and culture conditions appropriate to plant cells. Because of the diversity of cell types species and culture methods much of this volume is devoted to the culture of particular cell types and to the regeneration of these cells into whole plants. Special attention is also given to the genetic modification of plants as well as to the economic significance of plant products. Chapters cover a wide range of topics and techniques including: tissue culture media and selection cryopreservation callus culture techniques organ culture embryogenesis batch culture large-scale culture hormonal control fertilization techniques gene transfer cell immobilization production systems cell product purification DNA expression electrofusion of plant cells mutant selection mutagenesis techniques automation transfer of nuclei protoplast culture media analysis micropropagation. A detailed appendix lists the formulas for the most commonly employed plant cell media.Comprehensive easy to follow and a pleasure to use Pollard and Walker's Plant Cell and Tissue Culture is an essential tool for everyone--at all levels of proficiency and experience--involved in plant culture.

The first volume in this Methods Molecular Biology series, Proteins (1984), concentrated on basic techniques for the analysis and purification of peptides and proteins. As the series developed, more specialized volumes on proteins were introduced, such as those on Immunochemical Protocols (vol. 10), Practical Protein Chro- tography (vol. 11), Analysis Glycoprotein Biomedicine (vol. 14), Protein-DNA Interactions (vol. 30), Biomembrane Protocols (vols. 19 and 27), Analyses and Methods (vol. 17), and Optical Spectroscopy, Microscopy, and Macroscopic Techniques (vol. 22). Further specialist volumes on peptides, monoclonal antibodies, immunoassays, ELISA, protein engineering, protein stability, mass spectrometry of proteins, automated sequence analysis, and protein NMR are currently in preparation. Since it is now a decade since the initial volume was published, it seems an especially appropriate moment to extensively reorganize, update, and revise the earlier volume.In an attempt to be more c- prehensive in our coverage, this current volume, Basic Protein and Peptide Protocols, is totally committed to basic analytical methods; a planned companion volume will later concentrate on preparative techniques. Those analytical techniques requiring expensive speci- ized instrumentation, such as NMR, mass spectrometry, X-ray cr- tallography, spectroscopy, and automated sequence analysis, are not described here, but in the appropriate specialized volumes listed above.

This book aims to describe the current state of knowledge and possible future developments in a number of major areas of research into the nature, causes and treatment of cancer. The contributing authors have been encouraged to discuss their subjects at the molecular level. It will become apparent to the reader that considerable developments in the understanding of the fundamental nature of cancer, in molecular terms, are constantly being made. This is particularly the case in the area of oncogene research where differences between tumour and normal cells can now be defined in terms of altered expression of DNA sequences. An understanding of the methods available for detecting cancer, of the process of carcinogenesis and of the means available for treating cancer can only be achieved with a precise knowledge of the basic biochemical and molecular processes involved. Since it is all to easy for the research scientist to become totally absorbed within the specialised area of research in which he is involved, the first chapter is an attempt to encourage a broader field of vision by introducing the clinician's view of the cancer problem, which illustrates the broad spectrum of basic problems that need to be solved by the cancer researcher.

For many years I performed tissue culture in large scientific insti- tions that had a great deal of infrastructure. When I set up a tissue l- oratory outside such an infrastructure, however, I found there was a shortage of easily accessible information about the basic needs, reagents, and techniques for establishing such a facility. Much had to be done by trial and error or gleaned from originalpapers. Consequently, I felt that a methods book covering a wide variety of techniques from basic culture to the most sophisticated cell analysis would be a very valuable addition to the scientific literature. In the interim, several useful books (listed in Chapter I of this volume) did appear, but none entirely fitted the bill and some are now somewhat dated. Then, in 1984, the first of the Methods in Molecular Biology volumes from Humana Press was published with its step-by-step recipe approach. This format appealed to me, and so I c- tacted John Walker, the series editor, about including cell culture in this series. The result was that we embarked upon a single volume covering both plant and animal cell culture. Such was the richness of the material that this project soon divided itself into separate volumes on animal cell (Volume 5) and plant cell (Volume 6) culture. In this volume (Volume 5), therefore, we have aimed to describe a variety of basic techniques and culture conditions for a range of cell types.

This important handbook provides a number of novel mass spectrometry and LC-MS techniques central to structural and functional proteomics that are needed to deduce the function of newly discovered protein sequences. The use of these techniques will lead to achieving the ultimate goal of proteomics, namely to catalog the identity and funtion of all proteins in living organisms.

Recent advances in the biosciences have led to a range of powerful new technologies, particularly nucleic acid, protein and cell-based methodologies.
