Revised and Expanded Handbook Provides Comprehensive Introduction and Complete Instruction for Sample Preparation in Vital Category of Bioanalysis. Following in the footsteps of the previously published Handbook of LC-MS Bioanalysis, this book is a thorough and timely guide to all important sample preparation techniques used for quantitative Liquid Chromatography—Mass Spectrometry (LC-MS) bioanalysis of small and large molecules. LC-MS bioanalysis is a key element of pharmaceutical research and development, post-approval therapeutic drug monitoring, and many other studies used in human healthcare. While advances are continually being made in key aspects of LC-MS bioanalysis such as sensitivity and throughput, the value of research/study mentioned above is still heavily dependent on the availability of high-quality data, for which sample preparation plays the critical role. Thus, this text provides researchers in industry, academia, and regulatory agencies with detailed sample preparation techniques and step-by-step protocols on proper extraction of various analyte(s) of interest from biological samples for LC-MS quantification, in accordance with current health authority regulations and industry best practices. The three sections of the book with a total of 26 chapters cover topics that include: • Current basic sample preparation techniques (e.g., protein precipitation, liquid-liquid extraction, solid-phase extraction, salting-out assisted liquid-liquid extraction, ultracentrifugation and ultrafiltration, microsampling, sample extraction via electromembranes) • Sample preparation techniques for uncommon biological matrices (e.g., tissues, hair, skin, nails, bones, mononuclear cells, cerebrospinal fluid, aqueous humor) • Crucial aspects of LC-MS bioanalytical method development (e.g., pre-analytical considerations, derivation strategies, stability, non-specific binding) in addition to sample preparation techniques for challenging molecules (e.g., lipids, peptides, proteins, oligonucleotides, antibody-drug conjugates) “Sample Preparation in LC-MS Bioanalysis” will prove a practical and highly valuable addition to the reference shelves of scientists and related professionals in a variety of fields, including pharmaceutical and biomedical research, mass spectrometry, and analytical chemistry, as well as practitioners in clinical pharmacology, toxicology, and therapeutic drug monitoring.

An informative and comprehensive book on the applications and techniques of dried blood spot sampling Dried blood spot (DBS) sampling involves the collection of a small volume of blood, via a simple prick or other means, from a study subject onto a cellulose or polymer paper card, which is followed by drying and transfer to the laboratory for analysis. For many years, this method of blood sample collection has been extensively utilized in some important areas of human healthcare (for example, newborn screening for inherited metabolic disorders and HIV-related epidemiological studies). Because of its advantages over conventional blood, plasma, or serum sample collection, DBS sampling has been valued by the pharmaceutical industry in drug research and development. Dried Blood Spots: Applications and Techniques features contributions from an international team of leading scientists in the field. Their contributions present a unique resource on the history, principles, procedures, methodologies, applications, and emerging technologies related to DBS. Presented in three parts, the book thoroughly examines: • Applications of DBS sampling and associated procedures and methodologies in various human healthcare studies • Applications and perspectives of DBS sampling in drug research and development, and therapeutic drug monitoring • New technologies and emerging applications related to DBS sampling and analysis Dried Blood Spots: Applications and Techniques is a valuable working guide for researchers, professionals, and students in healthcare, medical science, diagnostics, clinical chemistry, and pharmaceuticals, etc.

The first book to offer a blueprint for overcoming the challenges to successfully quantifying biomarkers in living organisms. The demand among scientists and clinicians for targeted quantitation experiments has experienced explosive growth in recent years. While there are a few books dedicated to bioanalysis and biomarkers in general, until now there were none devoted exclusively to addressing critical issues surrounding this area of intense research. Target Biomarker Quantitation by LC-MS provides a detailed blueprint for quantifying biomarkers in biological systems. It uses numerous real-world cases to exemplify key concepts, all of which were carefully selected and presented so as to allow the concepts they embody to be easily expanded to future applications, including new biomarker development. “Target Biomarker Quantitation by LC-MS” primarily focuses on the assay establishment for biomarker quantitation-a critical issue rarely treated in depth. It offers comprehensive coverage of three core areas of biomarker assay establishment: the relationship between the measured biomarkers and their intended usage; contemporary regulatory requirements for biomarker assays (a thorough understanding of which is essential to producing a successful and defendable submission); and the technical challenges of analyzing biomarkers produced inside a living organism or cell. • Covers the theory of and applications for state-of-the-art mass spectrometry and chromatography and their applications in biomarker analysis • Features real-life examples illustrating the challenges involved in target biomarker quantitation and the innovative approaches which have been used to overcome those challenges • Addresses potential obstacles to obtain effective biomarker level and data interpretation, such as specificity establishment and sample collection • Outlines a tiered approach and fit-for-purpose assay protocol for target biomarker quantitation • Highlights the current state of the biomarker regulatory environment and protocol standards “Target Biomarker Quantitation by LC-MS” is a valuable resource for bioanalytical scientists, drug metabolism and pharmacokinetics scientists, clinical scientists, analytical chemists, and others for whom biomarker quantitation is an important tool of the trade.
