The introduction of high-performance liquid chromatography (HPLC) to the analysis of peptides and proteins some 25 years ago revolutionized the biological sciences by enabling the rapid and sensitive analysis of peptide and protein structure through the exquisite speed, sensitivity, and resolution that can be easily obtained. Today, HPLC in its various modes has become the pivotal technique in the characterization of peptides and proteins and currently plays a critical role in both our understanding of biological processes and in the development of peptide- and protein-based pharmaceuticals. The number of applications of HPLC in peptide and protein purification continues to expand at an extremely rapid rate. Solid-phase peptide synthesis and recombinant DNA techniques have allowed the production of large quantities of peptides and proteins that need to be highly purified. HPLC techniques are also used extensively in the isolation and characterization of novel proteins that will become increasingly important in the postgenomic age. The design of multidimensional purification schemes to achieve high levels of product purity further demonstrates the power of HPLC techniques not only in the characterization of cellular events, but also in the production of pepti- and protein-based therapeutics. HPLC continues to be at the heart of the analytical techniques with which scientists in both academia and in industry must arm themselves to be able to fully characterize the identity, purity, and potency of peptides and proteins.

This book is dedicated to the characterization of peptides and their applications for the study of biochemical systems. The contributing authors are all leaders in the field of peptide research. Part I, Characterization, presents the most recent advances in select analytical techniques. Part II, Application, presents a variety of specific applications for synthetic peptides. This book is an indispensable aid in the pursuit of new directions in peptide research.

Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were: 1. the dependence of scientific progress in biology on the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete that it is difficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be just as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a way that made description, as applied to plant material, complete in itselfwith little need to consult other publications. Contributing authors have attempted to follow these guidelines in this New Series of volumes.

How to synthesize native and modified proteins in the test tube With contributions from a panel of experts representing a range of disciplines, Total Chemical Synthesis of Proteins presents a carefully curated collection of synthetic approaches and strategies for the total synthesis of native and modified proteins. Comprehensive in scope, this important reference explores the three main chemoselective ligation methods for assembling unprotected peptide segments, including native chemical ligation (NCL). It includes information on synthetic strategies for the complex polypeptides that constitute glycoproteins, sulfoproteins, and membrane proteins, as well as their characterization. In addition, important areas of application for total protein synthesis are detailed, such as protein crystallography, protein engineering, and biomedical research. The authors also discuss the synthetic challenges that remain to be addressed. This unmatched resource: Contains valuable insights from the pioneers in the field of chemical protein synthesis Presents proven synthetic approaches for a range of protein families Explores key applications of precisely controlled protein synthesis, including novel diagnostics and therapeutics Written for organic chemists, biochemists, biotechnologists, and molecular biologists, Total Chemical Synthesis of Proteins provides key knowledge for everyone venturing into the burgeoning field of protein design and synthetic biology.

Leading scientists offer an unprecedented suite of master protocols for analyzing neuropeptide structure and function using optimized classic methods and the latest state-of-the-art techniques. This comprehensive collection includes valuable techniques for extracting and purifying neuropeptides from biological sources, for their sequence determination by Edman degradation and PCR, and for the solid-phase synthesis and purification of peptides and peptide analogs. Also covered are physical techniques for the characterization of synthetic or natural peptides, methods for immunocytochemical sample preparation and visualization at both light and electron levels, and techniques for neuropeptide-receptor interaction. Chapters on molecular modeling, radioisotopic labeling, production of antisera, the measurement of efflux from brain to blood, and the assay and inhibition of neuropeptidases complete this indispensable collection of readily reproducible protocols.

The powerful, efficient technique of high performance liquid chromatography (HPLC) is essential to the standardization of plant-based drugs, identification of plant material, and creation of new herbal medicines. Filling the void in this critical area, High Performance Liquid Chromatography in Phytochemical Analysis is the first book to give a comp

High-Performance Liquid Chromatography of Proteins and Peptides contains the proceedings of the first International Symposium on High-Performance Liquid Chromatography of Proteins and Peptides, held in Washington, D.C., on November 16-17, 1981. The symposium focused on the use of high-performance liquid chromatography (HPLC) in the analysis, characterization, and isolation of peptides and proteins and encompassed six sessions covering size exclusion, ion exchange, and reversed phase chromatography, as well as the use of high-performance liquid chromatography (HPLC) in protein structural studies and peptide isolation. This book is comprised of 28 chapters and begins with a discussion on the status of high-performance ion-exchange chromatography of proteins, followed by an analysis of peptic fragmentation of human immunoglobulin G using HPLC. The physicochemical basis of peptide retention with chemically bonded hydrocarbonaceous silicas and the isolation of biologically active peptides from tissue extracts are also examined. Subsequent chapters explore some additional applications of HPLC, such as cord blood screening for hemoglobin disorders; purification of commercial trypsin and chymotrypsin; characterization of human alcohol dehydrogenase isoenzymes; and structural studies of neurophysins, photolabeled derivatives, and biosynthetic precursors. This monograph should be of value to students and researchers interested in the use of HPLC to study proteins and peptides.
