Book excerpt: This thoroughly revised edition of the book demonstrates principle and instrumentation of each technique routinely used in biotechnology. Like the previous edition, the second edition also follows non-mathematical approach. Three aspects of each technique including principle, methodology with knowledge of different parts of an instrument; and applications have now been discussed in the text. For the beginners, the book will help in building a strong foundation, starting from the preparation of solutions, extraction, separation and analysis of biomolecules to the characterisation by spectroscopic methods—the full gamut of biological analysis. NEW TO THE SECOND EDITION • Incorporates two new chapters on 'Radioisotope Tracer Techniques' and 'Basic Molecular Biology Techniques and Bioinformatics'. • Comprises a full chapter on 'Fermentation and Bioreactors' Design and Instrumentation' (the revised and updated version of Miscellaneous Methods of the previous edition). • Contains a number of pictorial illustrations, tables and worked-out examples to enhance students' understanding of the topics. • Includes chapter-end review questions. TARGET AUDIENCE • B.Sc./B.Tech (Biotechnology) • M.Sc./M.Tech (Biotechnology)
