This book was released on 2008-02-04 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescent nucleic acid probes, which use energy transfer, include such constructs as molecular beacons, molecular break lights, Scorpion primers, TaqMan probes, and others. These probes signal detection of their targets by changing either the intensity or the color of their fluorescence. Not surpr- ingly, these luminous, multicolored probes carry more flashy names than their counterparts in the other fields of molecular biology. In recent years, fluor- cent probes and assays, which make use of energy transfer, have multiplied at a high rate and have found numerous applications. However, in spite of this explosive growth in the field, there are no manuals summarizing different p- tocols and fluorescent probe designs. In view of this, the main objective of Fluorescent Energy Transfer Nucleic Acid Probes: Designs and Protocols is to provide such a collection. Oligonucleotides with one or several chromophore tags can form fluor- cent probes capable of energy transfer. Energy transport within the probe can occur via the resonance energy transfer mechanism, also called Förster tra- fer, or by non-Förster transfer mechanisms. Although the probes using Förster transfer were developed and used first, the later non-Förster-based probes, such as molecular beacons, now represent an attractive and widely used option. The term “fluorescent energy transfer probes” in the title of this book covers both Förster-based fluorescence resonance energy transfer (FRET) probes and probes using non-FRET mechanisms. Energy transfer probes serve as molecule-size sensors, changing their fluorescence upon detection of various DNA reactions.

This book was released on 2015 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence spectroscopy is a popular technique that has been particularly useful in probing biological systems, especially with the invention of single molecule fluorescence. For example, Förster resonance energy transfer (FRET) is one tool that has been helpful in probing distances and conformational changes in biomolecules. In this work, important properties necessary in the quantification of FRET were investigated while FRET was also applied to gain insight into the dynamics of biological molecules. In particular, dynamics of damaged DNA was investigated. While damages in DNA are known to affect DNA structure, what remains unclear is how the presence of a lesion, or multiple lesions, affects the flexibility of DNA, especially in relation to damage recognition by repair enzymes. DNA conformational dynamics was probed by combining FRET and fluorescence anisotropy along with biochemical assays. The focus of this work was to investigate the relationship between dynamics and enzymatic repair. In addition, to properly quantify fluorescence and FRET data, photophysical phenomena of fluorophores, such as blinking, needs to be understood. The triplet formation of the single molecule dye TAMRA and the photoisomerization yield of two different modifications of the single molecule cyanine dye Cy3 were examined spectroscopically to aid in accurate data interpretation. The combination of the biophysical and physiochemical studies illustrates how fluorescence spectroscopy can be used to answer biological questions.

Available in PDF, EPUB and Kindle. Book excerpt: Interest in developing probes capable of targeting chromosomal DNA in cells has grown to meet diagnostic and therapeutic needs. DNA has a stable, predicable double-stranded structure that has been the subject of study to identify agents that can specifically bind to the duplex (CHAPTER 1). Success stories from probe technologies such as triplex-forming oligonucleotides, peptide nucleic acids (PNAs), and minor-groove-binding polyamides have been well-characterized. However, they suffer limits of detection along with challenging experimental conditions requirements (homopurine targets; denaturing steps; low ionic strengths; short target sequences). The newly discovered CRISPR-Cas9 has garnered much attention. However, the approach requires transfection of plasmids encoding CRISPR-Cas9 components. To address these shortcomings, our laboratory has developed Invader probes. Placement of 2'-O-(pyren-1-yl)methyl RNA monomers in +1 interstrand zipper arrangements destabilizes the probe duplex as the intercalating pyrene moieties vie for the same space between two Watson-Crick base pairs. These 'energetic hotspots' activate the double-stranded probe and, in concert with the high affinity for complementary DNA (cDNA) displayed by individual probe strands, provide the driving force for recognition of mixed-sequence target sites. The capabilities and features of Invader probes for specific detection of chromosomal DNA in fluorescent in situ hybridization (FISH) assays at near physiological conditions were statistically analyzed. Based on these results, optimized Invader probes were synthesized and showed improved efficiency in chromosomal DNA detection (CHAPTER 2). Moreover, the combination of Invader FISH probes with the powerful detection properties of flow cytometry was used to quantify thousands of specifically labelled isolated nuclei, offering a potential advantage over the laborious microscope evaluation of detection (CHAPTER 3).

This book was released on 2008-11-26 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a unique source of information on the present state of the exciting field of molecular cytogenetics and how it can be applied in research and diagnostics. The basic techniques of fluorescence in situ hybridization and primed in situ hybridization (PRINS) are outlined, the multiple approaches and probe sets that are now available for these techniques are described, and applications of them are presented in 36 chapters by authors from ten different countries around the world. The book not only provides the reader with basic and background knowledge on the topic, but also gives detailed protocols that show how molecular cytogenetics is currently performed by specialists in this field. The FISH Application Guide initially provides an overview of the (historical) development of molecular cytogenetics, its basic procedures, the equipment required, and probe generation. The book then describes tips and tricks for making different tissues available for molecular cytogenetic studies. These are followed by chapters on various multicolor FISH probe sets, their availability, and their pot- tial for use in combination with other approaches. The possible applications that are shown encompass the characterization of marker chromosomes, cryptic cytogenetic aberrations and epigenetic changes in humans by interphase and metaphase cyto- netics, studies of nuclear architecture, as well as the application of molecular cytogenetics to zoology, botany and microbiology.

Download or read book The Functional Nucleus written by David P. Bazett-Jones and published by Springer. This book was released on 2016-10-17 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an in-depth overview on nuclear structure and function. It clearly shows that the epigenome and the three-dimensional organization of the nucleus are not independent properties. The intimate relationship between the location and the epigenetic modifications of gene loci is highlighted. Finally, it shows that the complex three-dimensional organization of the nucleus is not just of academic interest: The structure, composition and function of virtually all of the sub-nuclear compartments identified so far can be implicated to a list of human genetic diseases. Hence, a detailed elucidation of how these domains are assembled and function will provide new opportunities for therapeutic intervention in clinical practice.
Download or read book Human Chromosomes written by Eeva Therman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, like the two previous editions, was written as an introduction to human cytogenetics, but it could also be used as a text for a general cytogenetics course, since chromosome structure and behavior are similar in all eukaryotes. Many examples in this book are from organisms other than humans, reflecting our combined backgrounds of molecular and bacterial genetics, and plant and animal cytogenetics. In the rapidly expanding field of human cytogenetics, certain subjects, for instance clinical and cancer cytogenetics, are now covered in recently published, thousand-page volumes. In this book, such subjects are presented only in outline. The enormous growth of information has also made the choice of topics and of examples to illustrate them even more arbitrary and subjective than in the previous editions. Apart from a few pages here and there, the text has been rewritten. Major parts, especially those on molecular matters, have been added. This book would not exist without the dedicated participation of Mrs. Barbara Susman. She has been involved in the project from the planning stages to the final proofreading. She has done the extensive literature research, designed most of the tables and illustrations, and edited and typed the text. For discussions and suggestions we are indebted to many colleagues. We wish especially to mention Drs. Lassi Alvesalo, Evelyn M. Kuhn, and Renata Laxova, who have critically read selected parts of the book, and Dr. Carter Denniston, who has read the whole text.

Download or read book Protocols for Oligonucleotides and Analogs written by Sudhir Agrawal and published by Springer Science & Business Media. This book was released on 1993-08-31 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: When first conceived, not only was the aim of Protocols for Oligo nucleotides and Analogs to provide wide coverage of the ohgonuc- otide chemistry field for readers who are well versed within the field, but also to give investigators just entering into the field a new perspective. The very first book on this topic was edited and published by Michael Gait in 1984, in whose laboratory I encountered the newer aspects of oligonucleotide chemistry. Since then, oligonucleotide research has developed to such an extent that its uses extend far beyond basic studies, and now find wide application throughout clinical science as well. Until recently, the major application of oligonucleotides has been in the area of DNA-based diagnostic and "antisense oligonucleotid- based therapeutic approaches. However, oligonucleotides are now also being used as therapeutic agents and are thus frequently found in clinical trials in humans. Synthesis of unmodified oligonucleotides using automated synthe sizers has become a common practice in numerous laboratories. How ever, improvements on the existing techniques and the introduction of ever newer methods for oligonucleotide synthesis is constantly driving ahead in the leading research laboratories. And several new oligonucle otide analogs have been synthesized and studied for their individual prop erties in recent years. The present volume strives to bring the readers the most up-to-date information on the newest aspects of synthesis of oligo nucleotides and their analogs. A separate volume covers synthesis of oligonucleotide conjugates, along with most of the analytical techniques presently used for analysis of oligonucleotides.
