Advances in Immunoassay Technology by Norman Chiu,Theodore K. Christopoulos Pdf
From the basic in vitro study of a specific biomolecule to the diagnosis or prognosis of a specific disease, one of the most widely used technology is immunoassays. By using a specific antibody to recognize the biomolecule of interest, relatively high specificity can be achieved by immunoassays, such that complex biofluids (e.g. serum, urine, etc.) can be analyzed directly. In addition to the binding specificity, the other key features of immunoassays include relatively high sensitivity for the detection of antibody-antigen complexes, and a wide dynamic range for quantitation. Over the past decade, the development and applications of immunoassays have continued to grow exponentially. This book focuses on some of the latest technologies for the development of new immunoassays.
Recent Advances in Immunoassays by Samar K. Kundu,Kundu Ph D Pdf
Immunoassay is a biochemical method that measures the presence or concentration of an analyte referred as an antigen in a solution through the use of an antibody or immunoglobulin. Immunoassays are now very widely used in the clinical laboratory, either because no other type of assay system is feasible or because they are often the most effective and suitable of the possible analytical methods. The major trend has been away from liquid-phase assays involving radioisotopic labels, towards fast homogeneous or solid-phase assays capable of operation anywhere; and towards precise and reliable non-isotopic, automated or semi-automated laboratory assays, often with detection limits measured in pico- or attomoles. The use of monoclonal antibodies is now widespread, and the methodologies of labels and of solid-phase components are much more sophisticated. New assay formulations, novel homogeneous systems, immunosensors, free-analyte assays, ultra-sensitive detection systems are being developed. Recent trends has been to enhance the sensitivity of the assays that may also have applications in measurement of other tumor markers, providing earlier detection of cancer or of relapse, Alzheimer's disease and in measurement of certain cardiac markers. More importantly, it is believed that high-sensitivity assays are expected to enable about a 50-fold expansion in the number of protein markers that can be analyzed in the clinical lab. At present, due to the sensitivity limitations of existing immunoassays of about 10-15 molar, only about 2,000 proteins are routinely analyzed by clinical labs. However, about 100,000 proteins are believed to exist in human blood, most of which are not analyzed due to limitations of existing assays. New high-sensitivity tests could potentially drive a significant expansion of the immunoassay market by enabling an entirely new set of markers to be analyzed. The present book is intended to overview different immunoassays including the most recent development trend
Immunoassays by Richard O'Kennedy,Caroline Murphy Pdf
The concept behind this book is to provide a detailed and practical overview of the development and use of immunoassays in many different areas. Immunoassays are analytical tests that utilise antibodies to measure the amount, activity or identity of an analyte. This book is designed to provide a critical and helpful insight into the subject and to give the user practical information that may be of assistance in assay format selection, antibody generation/selection and choice of appropriate detection strategies. It is comprised of 13 chapters written by highly experienced researchers in the fields of antibody-based research, immunoassay development, assay validation, diagnostics and microfluidics. Beginning with a comprehensive survey of antibodies, immunoassay formats and signalling systems, the book elucidates key topics related to the development of an ideal antibody-based sensor, focuses on the important topic of surface modification, explores key parameters in the immobilisation of antibodies onto solid surfaces, discusses the move to ‘lab-on-a-chip’-based devices and investigates the key parameters necessary for their development. Three of the chapters are dedicated to the areas of clinical diagnostics, infectious disease monitoring and food security, where immunoassay-based applications have become highly valuable tools. The future of immunoassays, including next-generation immunoassays, electrochemical-immunoassays and ‘lab-on-a-chip’-based systems, is also discussed. The book also covers the use of optical detection systems (with a focus on surface plasmon resonance) in immunoassays, provides a compilation of important, routinely used immunoassay protocols and addresses problems that may be encountered during assay development.

Advanced Techniques in Immunoassays by Jim Wang Pdf
Immunoassays are introduced in this book in a very sophisticated and concise manner. From the elementary in vitro analysis of a particular biomolecule to the diagnosis or prognosis of a particular disease, one of the most broadly practiced technologies is immunoassays. With the help of a particular antibody to identify the biomolecule of interest, comparatively high specificity can be attained by immunoassays, so that complex biofluids (e.g. serum, urine, etc.) can be examined directly. Along with the binding specificity, the other essential characteristics of immunoassays are relatively high sensitivity for the detection of antibody-antigen complexes, and a broad dynamic spectrum for quantitation. This book targets some of the recent technologies for the advancement of new immunoassays which, over the past decade, have continued to grow aggressively in their advancement and applications.
