The Experimental protocols of Immunology & Molecular Biology are presented so as to be readily used at the laboratory bench. Although a number of the procedures described represent the tried and trusted, we have striven to include variants on existing technologies that an experiment can be performed. These step-by-step protocols are intended to be concise and easy to follow. Suggestions to successfully apply the procedures are included, along with recommended materials. A special feature is that, in addition to the protocols, important background information and representative results of applying the methods are given. The aim of this book to provide a self-contained laboratory manual which will be useful to Graduate, Post Graduates & Research Scholars of Life sciences of various universities and colleges.
