The photophysical and photochemical properties of probes in biological and in model systems are topics of intense current research. The wavelength, intensity, time and polarisation dependence of fluorescence probes can provide information on properties as diverse as electric fields and changes in conformation and may be used in the formidable task of establishing structure-function relationships in proteins and cell membranes. The wide scope of interactions which can be studied by these fluorescent molecules is illustrated in the articles in this volume which are based on talks, although much extended and updated, given at a meeting on 'Fluorescence Probes in Proteins and Membranes' held in the Royal Institution in November 1979.

The most complete fluorescent labeling and detection reference available, The Molecular Probes HandbookA Guide to Fluorescent Probes and Labeling Technologies contains over 3,000 technology solutions representing a wide range of biomolecular labeling and detection reagents. The significantly revised 11th Edition features extensive references, reorganized content, and new technical notes and product highlights.

A self-contained treatment of the latest fluorescence applications in biotechnology and the life sciences This book focuses specifically on the present applications of fluorescence in molecular and cellular dynamics, biological/medical imaging, proteomics, genomics, and flow cytometry. It raises awareness of the latest scientific approaches and technologies that may help resolve problems relevant for the industry and the community in areas such as public health, food safety, and environmental monitoring. Following an introductory chapter on the basics of fluorescence, the book covers: labeling of cells with fluorescent dyes; genetically encoded fluorescent proteins; nanoparticle fluorescence probes; quantitative analysis of fluorescent images; spectral imaging and unmixing; correlation of light with electron microscopy; fluorescence resonance energy transfer and applications; monitoring molecular dynamics in live cells using fluorescence photo-bleaching; time-resolved fluorescence in microscopy; fluorescence correlation spectroscopy; flow cytometry; fluorescence in diagnostic imaging; fluorescence in clinical diagnoses; immunochemical detection of analytes by using fluorescence; membrane organization; and probing the kinetics of ion pumps via voltage-sensitive fluorescent dyes. With its multidisciplinary approach and excellent balance of research and diagnostic topics, this book is an essential resource for postgraduate students and a broad range of scientists and researchers in biology, physics, chemistry, biotechnology, bioengineering, and medicine.

This new volume, number 123, of Methods in Cell Biology looks at methods for quantitative imaging in cell biology. It covers both theoretical and practical aspects of using optical fluorescence microscopy and image analysis techniques for quantitative applications. The introductory chapters cover fundamental concepts and techniques important for obtaining accurate and precise quantitative data from imaging systems. These chapters address how choice of microscope, fluorophores, and digital detector impact the quality of quantitative data, and include step-by-step protocols for capturing and analyzing quantitative images. Common quantitative applications, including co-localization, ratiometric imaging, and counting molecules, are covered in detail. Practical chapters cover topics critical to getting the most out of your imaging system, from microscope maintenance to creating standardized samples for measuring resolution. Later chapters cover recent advances in quantitative imaging techniques, including super-resolution and light sheet microscopy. With cutting-edge material, this comprehensive collection is intended to guide researchers for years to come. Covers sections on model systems and functional studies, imaging-based approaches and emerging studies Chapters are written by experts in the field Cutting-edge material

Fluorescent Probes in Cellular and Molecular Biology presents the most comprehensive evaluation of the theory, instrumentation, and practical applications of fluorescent probes available. It covers basic principles and discusses the use of fluorescent dyes as probes for solvent polarity, solvent viscosity, membrane fluidity, membrane potential, and ionic intracellular composition. This important also describes various applications of fluorescent labels and photolabels, fluorescent analogs, and fluorogenic substrates. No similar publication is devoted exclusively to fluorescent probes, making this an essential guide for anyone working with modern fluorescence techniques. The book is perfect for individuals working in the areas of photochemistry, photobiology, biology, biophysics, or biochemistry. It is also an excellent textbook for graduate students in biology, biophysics, and medicine.
