PCR, developed at Cetus Corporation/USA by Henry A. Erlich, Kary Mullis and Randall K. Saiki, is a very simple method for amplifying nucleic acids in vitro. The realization of this idea bases on the repetition of a set of three different temperatures and yields an increase of the target structure up to a factor of 106 to 1012. Therefore, this technique is predisposed for safe analysis and characterization of DNA and RNA sequences of interest, even where the starting amount of material is enormously small. Because of its sensitivity, speed and versatility this method is particularly suitable for investigations of oncogenes, tumor associated translocations, retroviral sequences, lymphokines and mainly the broad field of degenerative and inflammatory diseases of nervous system. PCR seems to be the technique which could overcome the two most important problems in that field: very small amount of material combined with the necessity of rapid diagnostic procedures in inflammatory infections. "PCR topics" will give an actual overview of basic and applied research fields on usage of polymerase chain reaction. All contributions to this book have been presented at an international congress on "Usage of Polymerase chain reaction in genetic and infectious diseases" which took place in june 1990 in Berlin. The editors wish to thank all participants for their contributions. We offer our thanks and gratitude to our coworkers and especially to our technical assistents Barbara Trampenau, Mirjana Wiirdemann and Hannelore Leonhard.

In this new edition, the editors have thoroughly updated and dramatically expanded the number of protocols to take advantage of the newest technologies used in all branches of research and clinical medicine today. These proven methods include real time PCR, SNP analysis, nested PCR, direct PCR, and long range PCR. Among the highlights are chapters on genome profiling by SAGE, differential display and chip technologies, the amplification of whole genome DNA by random degenerate oligonucleotide PCR, and the refinement of PCR methods for the analysis of fragmented DNA from fixed tissues. Each fully tested protocol is described in step-by-step detail by an established expert in the field and includes a background introduction outlining the principle behind the technique, equipment and reagent lists, tips on trouble shooting and avoiding known pitfalls, and, where needed, a discussion of the interpretation and use of results.
James D. Watson When, in late March of 1953, Francis Crick and I came to write the first Nature paper describing the double helical structure of the DNA molecule, Francis had wanted to include a lengthy discussion of the genetic implications of a molecule whose struc ture we had divined from a minimum of experimental data and on theoretical argu ments based on physical principles. But I felt that this might be tempting fate, given that we had not yet seen the detailed evidence from King's College. Nevertheless, we reached a compromise and decided to include a sentence that pointed to the biological significance of the molecule's key feature-the complementary pairing of the bases. "It has not escaped our notice," Francis wrote, "that the specific pairing that we have postulated immediately suggests a possible copying mechanism for the genetic material." By May, when we were writing the second Nature paper, I was more confident that the proposed structure was at the very least substantially correct, so that this second paper contains a discussion of molecular self-duplication using templates or molds. We pointed out that, as a consequence of base pairing, a DNA molecule has two chains that are complementary to each other. Each chain could then act ". . . as a template for the formation on itself of a new companion chain, so that eventually we shall have two pairs of chains, where we only had one before" and, moreover, " ...
Kary Mullis was awarded a Nobel Prize for inventing the PCR technique more than a decade ago in 1993. Since its "discovery", multiple adaptations and variations of the standard PCR technique have been described. This publication aims to provide the reader with a guide to the standard PCR technique and its many available variants, with particular emphasis being placed on the role of these PCR techniques in the clinical diagnostic laboratory (the central theme of this book).
This second volume focuses on PCR methods and PCR application specificities to the biotechnology and bioengineering field. New and updated chapters detail real-time PCR protocols, synthetic biology applications, pathogen detection, microfluidics, digital, multiplex detection recent advances. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, PCR: Methods and Protocols, Second Edition aims to be a useful and practical guide to new researchers and experts looking to expand their knowledge.
A thoroughly updated version of the successful first edition with a new chapter on Real-Time PCR, more prokaryotic applications, and more detail in the complex mutagenesis sections. Information on PCR applications in genomics and proteomics have been expanded and integrated throughout the text. There is also advice on available products and specific pointers to the most appropriate methods. As with the first edition, this will be an ideal practical introduction and invaluable guide to PCR and its applications.
Until the mid 1980s, the detection and quantification of a specific mRNA was a difficult task, usually only undertaken by a skilled molecular biologist. With the advent of PCR, it became possible to amplify specific mRNA, after first converting the mRNA to cDNA via reverse transcriptase. The arrival of this technique—termed reverse transcription-PCR (RT-PCR)—meant that mRNA suddenly became amenable to rapid and sensitive analysis, without the need for advanced training in molecular biology. This new accessibility of mRNA, which has been facilitated by the rapid accumulation of sequence data for human mRNAs, means that every biomedical researcher can now include measurement of specific mRNA expression as a routine component of his/her research plans. In view of the ubiquity of the use of standard RT-PCR, the main objective of RT-PCR Protocols is essentially to provide novel, useful applications of RT-PCR. These include some useful adaptations and applications that could be relevant to the wider research community who are already familiar with the basic RT-PCR protocol. For example, a variety of different adaptations are described that have been employed to obtain quantitative data from RT-PCR. Quantitative RT-PCR provides the ability to accurately measure changes/imb- ances in specific mRNA expression between normal and diseased tissues.
Hands-on laboratory experts present a set of "classic" PCR-based methods for the identification and detection of important animal and food microbial pathogens, including several zoonotic agents. These proven techniques can be precisely applied to a wide variety of microbes, among them Campylobacter spp., chlamydiae, toxigenic clostridia, Escherichia coli (STEC), Listeria monocytogenes, mycoplasmas, salmonellae, and Yersinia enterocolitica. Additional chapters review the specificity and performance of diagnostic PCR analysis, the pre-PCR processing of samples, the critical aspects of standardizing PCR methods, and the general issues involved in using PCR technology for microbial diagnosis.
PCR in Bioanalysis offers powerful PCR-based protocols and assays in actual use or potential use in clinical medicine and commercial biology. The main focus of the book is on the commercial applications of PCR, as opposed to basic research uses. Topics covered include the measurement of hormone levels using PCR, transcription factor isolation, detection of viruses using PCR, detection of tumor contamination of stem cells, evaluation of grafts for tumor cells, and more.
