Immunoassay techniques have become essential in various fields of pure and applied research. This volume of the well known Laboratory Techniques series will be of assistance to those who have plans or are making efforts to develop ultrasensitive enzyme immunoassays for antigens and antibodies. The volume describes factors limiting the sensitivity of noncompetitive solid phase enzyme immunoassays, methods to overcome difficulties limiting sensitivities, methods to perform ultrasensitive enzyme immunoassays as rapidly as possible, and protocols of enzyme labeling and enzyme assays as well as ultrasensitive enzyme immunoassays. Ultrasensitive and Rapid Enzyme Immunoassay, with its clear presentation and up-to-date information, will be essential to scientists in pharmaceutical companies and in applied research.

Each chapter of this book aims to explore the basic physical and chemical principles involved in the immunoassay techniques discussed. The book also looks at the optimization and limitations of methodology and concludes with a brief overview of the application of the performance of the technology.

Since the publication of the first edition of Chemistry of Protein Conjugation and Cross-Linking in 1991, new cross-linking reagents, notably multifunctional cross-linkers, have been developed and synthesized. The completion of the human genome project has opened a new area for studying nucleic acid and protein interactions using nucleic acid cross-linking reagents, and advances have also been made in the area of biosensors and microarray biochips for the detection and analysis of genes, proteins, and carbohydrates. In addition, developments in physical techniques with unprecedented sensitivity and resolution have facilitated the analysis of cross-linked products. Updated to reflect the advances of the 21st century, this book offers: An overview of the chemical principles underlying the processes of cross-linking and conjugation A thorough list of cross-linking reagents published in the literature since the first edition, covering monofunctional, homobifunctional, heterobifunctional, multifunctional, and zero-length cross-linkers Reviews of the use of these reagents in studying protein tertiary structures, geometric arrangements of subunits within complex proteins and nucleic acids, near-neighbor analysis, protein-to-protein or ligand–receptor interactions, and conformational changes of biomolecules Discusses the application of immunoconjugation for immunoassays, immunotoxins for targeted therapy, microarray technology for analysis of various biomolecules, and solid state chemistry for immobilizations

This book shows the various sandwich assays that are constructed from recognition molecules, such as antibodies, oligonucleotide sequences and aptamers, developed as a result of nano- and biotechnology advances. It consists of ten chapters presenting interesting examples of these assays, organized according to the type of analytic methods (colorimetric, fluorescence, electrochemical, etc.) and detected objects (protein, nucleic acid, small-molecule, ion, etc.). It also includes a chapter discussing the introduction of sandwich assays as biosensors for the detection of a range of targets. It is an interesting and useful resource for a wide readership in various fields of chemical science and nanotechnology.
