This detailed book examines experimental approaches used to investigate the regulation and function of phosphoinositides (PtdInsP), rare eukaryotic phospholipids with a broad role in biological processes such as signal transduction, cell migration and adhesion, cell growth, subcellular organization, and membrane trafficking. The combination of complementary biochemical, mass spectrometry, and imaging methods are instrumental for the detection and quantification of PtdInsP species, as well as induced dimerization methods, affinity precipitation or co-sedimentation with liposomes, protein insertion within lipid bilayers, and enzymatic assays, or through emerging methods like native mass spectrometry and microfluidics, all of which are touched upon in this volume. Written in the highly successful Methods in Molecular Biology format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratoryprotocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Phosphoinositides: Methods and Protocols provides detailed methodology for both specialist and novice researchers on a variety of complementary methods that have been instrumental in dissecting the regulation, dynamics, and function of PtdInsPs.

This detailed volume focuses on recent technological, computational, and biostatistical advances in the field of high-throughput metabolomics. Chapters encompass methods, platforms, and analytical strategies for steady state measurements and metabolic flux analysis with stable isotope-labeled tracers, in biological matrices of clinical relevance and model organisms. Mass spectrometry-based or orthogonal methods are discussed, along with computational and statistical methods to address data sparsity in high-throughput metabolomics approaches. As a part of the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, High-Throughput Metabolomics: Methods and Protocols provides tools that can bring about thenext generation of clinical biochemistry in a cost-effective, rigorous fashion, exponentially advancing our capacity to investigate nature while hastening the advent of personalized medicine.

Dieses Buch liefert einen sehr persönlichen Einblick in das Leben und Wirken von Felix Hoppe-Seyler. Er war durch seine Entdeckungen und seinen Einfluss auf die Entstehung eines neuen Forschungsgebietes, der Physiologischen Chemie oder Biochemie, eine der einflussreichsten Forscherpersönlichkeiten seiner Zeit. Hoppe-Seylers eigene Entdeckungen sind zahlreich. Sie schließen Erkenntnisse aus der Physiologie, der Pathologie und der Chemie ein. Im Mittelpunkt seiner Leistungen stehe aber die nie erlahmenden Bemühungen der Physiologischen Chemie, also der Wissenschaft von den chemischen Grundlagen der Biologie ihren Platz an den deutschen Universitäten zu erkämpfen. Seine Waffen waren die von ihm gegründete Zeitschrift für Physiologische Chemie und das Handbuch der Physiologischen- und Pathologischen Analyse. Georg Hoppe Seyler, ein Nachfahre, hat sich bemüht ein möglichst objektives, von überkommenen durch die Jahre veränderten Vorstellungen freies Bildauf der Grundlage von Briefen und Dokumenten zu zeichnen. Briefe des Nachlasses, Zitate von mit Felix Hoppe (-Seyler) arbeitenden Zeitgenossen die ihn als der Persönlichkeit und Wissenschaftler kennen lernten und seine Publikationen bilden den Hintergrund der kurzen Zusammenstellung.

Animal cell technology is a growing discipline of cell biology which aims not only to understand structures, functions and behaviors of differentiated animal cells but also to ascertain their abilities to be used for industrial and medical purposes. The goal of animal cell technology includes accomplishments of clonal expansion of differentiated cells with useful ability, optimization of their culture conditions, modulation of their ability for production of medically and pharmaceutically important proteins, and the application of animal cells to gene therapy and artificial organs. This Volume gives the readers a complete review of the present state of the art in Japan. The Proceedings will be useful for cell biologists, biochemists, molecular biologists, immunologists, biochemical engineers and other disciplines related to animal cell culture, working either in academic environments or in industries of biotechnology and pharmacy.

This book discusses the basics of nanotoxicity and gives a detailed account of methods used for toxicity evaluation of nanomaterials. It also gives indepth coverage of the effect of different types of nanomaterials, including organic and inorganic, on various aquatic animals, microorganisms and plants, and outlines recent challenges, regulatory frameworks and advances in nanotoxicity testing.

This detailed volume covers conventional MS-based ¿shotgun lipidomics¿ by which samples are introduced by infusion or loop injection, as well as LC-MS-based lipidomics, which are becoming increasingly important due to the ever-increasing demand for a complete and precise lipid analysis of the complex and diversified lipids in nature. The volume features protocols applying chemical reactions, the on-line photochemical reactions combined with various MS methods for comprehensive characterization of various lipid classes, and quantification of specific and rare lipids. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Mass Spectrometry-Based Lipidomics: Methods and Protocols serves asan invaluable guide for biochemists and mass spectroscopists who are interested in lipid studies.
