This is a quick-reference manual on practical aspects of immunoassay. Providing a theoretical and practical basis for modern applications of solid-phase immunoassays, this text brings together experts who have used ELISA and other assays in a variety of fields. Contributors offer step-by-step guidance on how to use the various techniques involved in immunoassay. These techniques are extemely useful to laboratory-based researchers and technicians working on the detection of allergy, the AIDS virus, autoimmunity, etc. Chapters analyze the solid-phase supports used, the amplification systems, and the quantitation and affinity of antibodies and discuss the applications of assays to biology, immunology, and microbiology.
