This book was released on 2012-12-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence and phosphorescence are proving to be extremely sensitive probes for elucidating conformation of proteins and nucleic acids and for studying molecular interactions. Newer instrumentation and techniques hold forth great promise for the future of these luminescence methods in biopolymer research. It must be noted, however, that the discovery that certain amino acids, purines, and pyrimidines emit fluorescence or phosphorescence is relatively recent, occurring within the last decade. Professor Konev is one of the pioneers in the application of these procedures to biopolymers and is highly qualified to write about this subject. This book, though written largely as a monograph of the author's own contributions, is also an excellent review of the subject. Of particular interest are the references to many important Russian papers in this field which have not been recognized in the Western literature. It is apparent from this book that fluorescence and phosphorescence methods are being used about as widely in Russia as elsewhere in the world and that we must not overlook these im portant contributions. Konev's studies on protein fluorescence have been widely recognized. It is of interest to learn about these and other of his applications. The last part of the book, which deals with fluorescence as a means to probe into the structure and conforma tion of macromolecules in intact cells, is most interesting. Aside from published symposia this book is the first written specifically about luminescence of biopolymers. Sidney Udenfriend Bethesda.

This book was released on 2012-12-06 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The choice of title for this collective volume reflects the desire of the editors and authors to make clear that, while the bulk of the material is concerned with luminescence, other aspects of the excited state have not been excluded. In the five years which have elapsed since the publication of the classical monograph of Konev, a wealth of new information has ap peared on the emission properties of proteins and nucleic acids. Indeed, since new publications in this area appear to be proliferating in a geometric ratio, this may be the last opportunity to provide a comprehensive summary of the field in a book which is not of prohibitive length. This is what we have attempted to do here. While the orientation of each chapter naturally reflects the interests and point of view of the author, there has been a general effort to present .a critical assessment of existing results and interpretations, rather than a compendium of data with minimal comment. Finally, it should be stressed that the rapid evolution of the subject at the time of writing makes it inevitable that the book will age to some degree over the next few years, although this will occur at differing rates for the various chapters. We can only hope that most of the material in this interim summing-up will prove resistant to the erosion of time and provide a solid foundation for further progress.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence spectroscopy and its applications to the physical and life sciences have evolved rapidly during the past decade. The increased interest in fluorescence appears to be due to advances in time resolution, methods of data analysis and improved instrumentation. With these advances, it is now practical to perform time-resolved measurements with enough resolution to compare the results with the structural and dynamic features of mac- molecules, to probe the structures of proteins, membranes, and nucleic acids, and to acquire two-dimensional microscopic images of chemical or protein distributions in cell cultures. Advances in laser and detector technology have also resulted in renewed interest in fluorescence for clinical and analytical chemistry. Because of these numerous developments and the rapid appearance of new methods, it has become difficult to remain current on the science of fluorescence and its many applications. Consequently, I have asked the experts in particular areas of fluorescence to summarize their knowledge and the current state of the art. This has resulted in the initial three volumes of Topics in Fluorescence Spectroscopy, which is intended to be an ongoing series which summarizes, in one location, the vast literature on fluorescence spectroscopy. These first three volumes are designed to serve as an advanced text. These volumes describe the more recent techniques and technologies (Volume 1), the principles governing fluorescence and the experimental observables (Volume 2), and applications in biochemistry and biophysics (Volume 3).
Download or read book Fluorescence and Phosphorescence Spectroscopy written by Stephen G Schulman and published by Elsevier. This book was released on 2017-05-17 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence and Phosphorescence Spectroscopy: Physicochemical Principles and Practice deals with the physicochemical principles and applications of fluorescence and phosphorescence spectroscopy in experimental biology and chemistry. Topics covered include the absorption of light by molecules; instrumentation for the measurement of fluorescence and phosphorescence; solvent and acidity effects on electronic spectra; and polarization of fluorescence and phosphorescence. Comprised of four chapters, this book begins with a discussion on photophysical processes in isolated molecules and molecules in solution, paying particular attention to thermal equilibration of electronically excited molecules, phototautomerism, and coordination by metal ions. The next chapter describes the instrumentation for measuring fluorescence and phosphorescence, which consists essentially of a light source to electronically excite the sample; a monochromator to separate the light of desired energy from the source; a sample compartment; a second monochromator to isolate the sample's fluorescence energy from the excitation energy; a photodetector to translate the fluorescent light into an electrical signal; and a readout system such as a galvanometer or a recorder, coupled with an amplifier to determine the intensity of fluorescent light that is emitted. The final chapter is devoted to various applications of fluorescence and phosphorescence spectroscopy, including the analysis of organic and inorganic compounds. This monograph is written primarily for analytical chemists and biological scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Photochemistry of Proteins and Nucleic Acids deals with photobiology. The book briefly introduces the principles of photochemistry, with a short discussion on absorption spectra and related absorbing structures, as well as on the general nature of photochemical reactions in solutions. The following information covers how proteins, nucleic acids, viruses, and their basic structures are chemically and physically affected when exposed to visible radiation and ultraviolet light. The book explains that the site of action of the ultraviolet light when applied to proteins in a small active center shows that other parts of the protein are also affected, considered as an energy transfer. Then the general conclusions pertaining to the physicochemical and chemical changes in nucleic acids through directed radiation doses that are big enough to induce modifications are enumerated. The text further explains that the physicochemical modifications, which occur when proteins are irradiated, can accompany loss in enzyme activity. The kinetics of inactivation of dry enzymes is compared to the photochemistry of enzymes in a solution. The inactivation of viruses is important as the process of replication can cause some formed viruses to spread in its environment, worsening the state of infection. Hence, the problem which components in a biological system absorb effective radiation is analyzed. The book is suitable for microbiologists, microchemists, and laboratory researchers and scientists dealing with infectious diseases.
Download or read book Protein Fluorescence written by Joseph R. Lacowicz and published by Springer Science & Business Media. This book was released on 2006-04-18 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intrinsic or natural fluorescence of proteins is perhaps the most complex area of biochemical fluorescence. Fortunately the fluorescent amino acids, phenylalanine, tyrosine and tryptophan are relatively rare in proteins. Tr- tophan is the dominant intrinsic fluorophore and is present at about one mole % in protein. As a result most proteins contain several tryptophan residues and even more tyrosine residues. The emission of each residue is affected by several excited state processes including spectral relaxation, proton loss for tyrosine, rotational motions and the presence of nearby quenching groups on the protein. Additionally, the tyrosine and tryptophan residues can interact with each other by resonance energy transfer (RET) decreasing the tyrosine emission. In this sense a protein is similar to a three-particle or mul- particle problem in quantum mechanics where the interaction between particles precludes an exact description of the system. In comparison, it has been easier to interpret the fluorescence data from labeled proteins because the fluorophore density and locations could be controlled so the probes did not interact with each other. From the origins of biochemical fluorescence in the 1950s with Prof- sor G. Weber until the mid-1980s, intrinsic protein fluorescence was more qualitative than quantitative. An early report in 1976 by A. Grindvald and I. Z. Steinberg described protein intensity decays to be multi-exponential. Attempts to resolve these decays into the contributions of individual tryp- phan residues were mostly unsuccessful due to the difficulties in resolving closely spaced lifetimes.
