In Free Radical and Antioxidant Protocols, seventy-six leading international authorities describe cutting-edge methodologies for quantifying free radical and antioxidant analytes in tissue and body fluids using experimental models and in vitro procedures. These user-friendly and easily reproducible techniques cover the essential tasks, including radical generating systems, direct measurement or trapping of reactive radical species and acute-phase proteins, and measurement of metabolic intermediates derived from the oxidation of lipids, proteins, and nucleic acids. There are also methods for the determination of vitamin, enzymatic, and water-soluble antioxidants, as well as of essential micronutrients and cofactors. The techniques take advantage of new instrumentation-probes, photon counting, chemiluminescence, and caged compounds, with an emphasis on HPLC-and are adaptable to a wide range of applications. Free Radical and Antioxidant Protocols provides state-of-the-art methodology and biotechnology in a convenient format for both academic and corporate biomedical scientists. The detailed, laboratory-tested free-radical assays, many of them presented here for the first time, will illuminate the study of both primary and secondary oxidative stress and contribute significantly to our understanding of the many disorders associated with this process.

Essential in biological functions like cell signaling and, when disturbed, a likely cause of disease, lipids have proven to be a vital force in cell biology. In Lipidomics: Methods and Protocols, an international panel of experts present a wide variety of reviewed as well as unpublished data on isolation techniques, structural analysis, lipid rafts, lipid trafficking and profiling, biomarkers, lipid peroxidation, biostatistics applied to lipids, software tools, and bioinformatics. These studies range from simple systems, such as in yeast, to complex biological models. Samples used in these studies include: mitochondria, microsomes, endosomal membranes, RBS and plasma membranes, vesicles, caveolae, liposomes, macrophages, meibum, brain, microglia, retina, adipose tissue, keratinocytes, pulmonary surfactant, and hepatic cultures. Volume 2 focuses on oxidized lipids, trafficking and profiling, software, bioinformatics, and biostatistics. Written in the highly successful Methods in Molecular Biology™ series format, the chapters include useful introductions to their respective topics, lists of the necessary equipment and materials, step-by-step, readily reproducible laboratory protocols, and authoritative notes on troubleshooting and avoiding common pitfalls. Comprehensive and cutting-edge, Lipidomics: Methods and Protocols will support researchers who wish to increase their utilization of lipidomics, which will certainly lead to more powerful technology, improved diagnostic-prognostic capabilities, and the identification of new valuable products.

It is now feasible to identify subcellular sites where oxidative stress reactions occur and to determine gene expression relevant to those complex pathways. In Oxidants and Antioxidants: Ultrastructure and Molecular Biology Protocols, a panel of world authorities present cutting-edge molecular and ultrastructure techniques for investigating the pathophysiology of oxidative stress. Described in step-by-step detail, these readily reproducible methods use the latest in immunodetection, X-ray diffraction, confocal microscopy, in situ hybridization, chemiluminescence, and cytofluorescence. Additional techniques take advantage of electron paramagnetic resonance, advanced glycation endproducts, Western blotting analysis, transcription factors, p47phox translocation, and microsphere delivery systems. The collection emphasizes the visual observation of free radicals or products altered by oxidative stress, and includes numerous in vivo, ex vivo, and in vitro applications. Two companion volumes, Oxidative Stress Biomarkers and Antioxidant Protocols (2002), and Free Radical and Antioxidant Protocols (1998), focus on the related biochemical and cellular biological methods. Authoritative and highly practical, Oxidants and Antioxidants: Ultrastructure and Molecular Biology Protocols provides a comprehensive collection of powerful ultrastructure and molecular tools for the evaluation of metabolic disorders linked to oxidative stress and the aging process.
