MolecularCloning has served as the foundation of technical expertise in labs worldwide for 30 years. No other manual has been so popular, or so influential. Molecular Cloning, Fourth Edition, by the celebrated founding author Joe Sambrook and new co-author, the distinguished HHMI investigator Michael Green, preserves the highly praised detail and clarity of previous editions and includes specific chapters and protocols commissioned for the book from expert practitioners at Yale, U Mass, Rockefeller University, Texas Tech, Cold Spring Harbor Laboratory, Washington University, and other leading institutions. The theoretical and historical underpinnings of techniques are prominent features of the presentation throughout, information that does much to help trouble-shoot experimental problems.
For the fourth edition of this classic work, the content has been entirely recast to include nucleic-acid based methods selected as the most widely used and valuable in molecular and cellular biology laboratories.
Core chapters from the third edition have been revised to feature current strategies and approaches to the preparation and cloning of nucleic acids, gene transfer, and expression analysis. They are augmented by 12 new chapters which show how DNA, RNA, and proteins should be prepared, evaluated, and manipulated, and how data generation and analysis can be handled.
The new content includes methods for studying interactions between cellular components, such as microarrays, next-generation sequencing technologies, RNA interference, and epigenetic analysis using DNA methylation techniques and chromatin immunoprecipitation. To make sense of the wealth of data produced by these techniques, a bioinformatics chapter describes the use of analytical tools for comparing sequences of genes and proteins and identifying common expression patterns among sets of genes.
Building on thirty years of trust, reliability, and authority, the fourth edition of Molecular Cloning is the new gold standardthe one indispensable molecular biology laboratory manual and reference source.
Dr. Tasuku Honjo graduated from Kyoto University Faculty of Medicine in 1966 (M.D.). After obtaining his Ph.D. in Biochimistry (Dr. O. Hayaishi), he spent 4 years in the U.S.A. as a postdoctoral fellow first in Carnegie Institution of Washington (Dr. D. Brown), and then in NIH (Dr. P. Leder) where he initiated studies on immunoglobulin genes. He returned to Tokyo University as an assistant professor in 1974, and then moved to Osaka University School of Medicine as Professor of Genetics in 1979. He succeeded to Dr. O. Hayaishi after his retirement at the Department of Medical Chemistry in Kyoto University. He also served as Dean of Medical School (1996-2000 and 2004-2005), and Executive Member of Council for Science and Technology Policy, Cabinet Office (2006-2012). Currently, he is Professor of Department of Immunology and Genomic Medicine, Kyoto University, and also Chairman of Board of Directors, Shizuoka Prefectural University Corporation.
Dr. Honjo is well known for his discovery of activation-induced cytidine deaminase that is essential for class switch recombination and somatic hypermutation. He has established the basic conceptual framework of class switch recombination starting from discovery of DNA deletion (1978) and S regions (1980), followed by elucidation of the whole mouse immunoglobulin heavy-chain locus. His contribution further extended to cDNA cloning of IL-4 and IL-5 cytokines involved in class switching and IL-2 receptor alpha chain. Aside from class switching recombination, he discovered PD-1 (program cell death 1), a negative coreceptor at the effector phase of immune response and showed that PD-1 modulation contributes to treatments of viral infection, tumor and autoimmunity. In addition, he is known to be a discoverer of RBP-J, a nuclear protein that interacts with the intracellular domain of Notch in the nucleus. Notch/RBP-J signaling has been shown to regulate a variety of cell lineage commitment including T and B cells.
For these contributions, Dr. Honjo has received many awards, including the Noguchi Hideyo Memorial Prize for Medicine (1981), Imperial Prize, Japan Academy Prize (1996), Robert Koch Prize (2012), and Order of Culture (2013). He is an honorary member of the American Association of Immunologists. He has been honored by the Japanese Government as a person of cultural merits (2000). He has also been elected as a foreign associate of National Academy of Sciences, USA in 2001, as a member of Leopoldina, the German Academy of Natural Scientists in 2003, and as a member of Japan Academy in 2005.
Furthermore Dr Reth has shown that receptors on the plasma membrane have a more complex structure than previously assumed. They are not freely diffusing on the cell surface but are organized in 50 to 150 nanometre sized membrane patches also called protein islands. The detailed analysis of the organization of receptors on the cellular membrane is a focus of research at the BIOSS Centre for Biological Signalling Studies, the cluster of excellence directed by Dr Reth since 2007.
Andreas Radbruch did his PhD at the Genetics Institute of the Cologne University, Germany, with Klaus Rajewsky. He later became Associate Professor there and was a visiting scientist with Max Cooper and John Kearney at the University of Alabama, Birmingham. In 1996, he became Director of the German Rheumatism Research Centre Berlin, a Leibniz Institute, and in 1998, Professor of Rheumatology at the Charit, the Medical Faculty of the Humboldt University of Berlin.
A biologist by education, Andreas Radbruch early on worked on somatic variants in myeloma and hybridoma cells lines, modeling antibody class switching and somatic hypermutation. In this context, his lab originally developed the MACS technology. Andreas Radbruch then showed that recombination is the physiological mechanism of class switching in vivo, in plasmablasts isolated ex vivo. Moreover, he could show that in vivo, class switch recombination is targeted to the same Ig class on both IgH loci of a cell, reflecting a tight control of targeting of recombination. An essential element of this control is transcription of recombinogenic sequences, and the processing of these switch (germline) transcripts, as became evident from targeted deletion of the control regions involved. The switch transcripts are induced by cytokines of T helper cells, e.g. interleukin-4. The Radbruch lab contributed essentially to our current understanding of the polarization and imprinting of T helper cells expressing interleukin-4 (Th2) versus those expressing interferon- (Th1).
The lab then addressed the organization of immunological memory as such. First they identified longlived (memory) plasma cells, mostly residing in bone marrow but also in secondary lymphoid organs and in inflamed tissues. They could show that these cells individually persist in dedicated survival niches, organized by CXCL12-expressing mesenchymal stroma cells. They identified different, dedicated niches for CD4+ and CD8+ memory T cells in the bone marrow, too, and could show that, at least in immune responses to vaccines, memory T cells are mostly maintained in bone marrow, resting in terms of proliferation and gene expression. Thus memory niches organize and maintain memory, and bone provides a privileged environment for resting memory cells. In chronic antibody-mediated diseases, Andreas Radbruchs lab identified pathogenic antibody-secreting memory plasma cells as critical mediators of chronicity, refractory to conventional immunosuppression, and thus representing a novel therapeutic target. Similarly, in chronic T cell-mediated diseases, the pathogenic T cells induce and adapt to chronicity. Recently, the Radbruch group has identified Twist1, HopX and the microRNAs miR-182 and miR148a as molecular adaptations of proinflammatory T cells to chronicity, and innovative therapeutic targets.
Andreas Radbruchs work has been recognized by the Carol Nachman Prize for Rheumatology (2011), an Advanced Grant of the European Research Council (ERC, 2010), the Federal Cross of Merit (2008) and the Aronson Award (2000). He is a member of the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW), the European Molecular Biology Organization (EMBO) and the German National Academy of Sciences Leopoldina.

Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules and to direct their replication within host organisms.[1] The use of the word cloning refers to the fact that the method involves the replication of one molecule to produce a population of cells with identical DNA molecules. Molecular cloning generally uses DNA sequences from two different organisms: the species that is the source of the DNA to be cloned, and the species that will serve as the living host for replication of the recombinant DNA. Molecular cloning methods are central to many contemporary areas of modern biology and medicine.[2]
