Immunochemical techniques are invaluable in all biological disciplines for detecting, estimating and isolating molecules and cells. The aim of this practical book is to provide scientists, whatever their specialty, with clear step-by-step details of immunochemical procedures. This third edition of Immunochemistry in Practice has been completely revised and updated; some chapters have been restructured and there are several new sections, a new chapter and many new illustrations. A revised layout has been adopted for improved ease of use.
