"Molecular Cloning: A Laboratory Manual" is the world's best-selling manual of molecular biology techniques and it has informed, educated and inspired hundreds of thousands of researchers since the publication of the first edition in 1989. "The Condensed Protocols" is a practical and manageable tool for use at the bench. It is a single-volume adaptation of the third edition of "Molecular Cloning: A Laboratory Manual" and is designed to be used in conjunction with "Molecular Cloning", not as a replacement for it. "The Condensed Protocols" contains the step-by-step portions of the protocols from "Molecular Cloning", accompanied by the appendices. Each protocol is cross-referenced to the appropriate pages in the original book: the reader is directed to the relevant sections in the original book to ensure that they understand the full context of their experiments. "The Condensed Protocols" is an affordable volume which offers individual investigators the opportunity to have their own personal collection of proven and recommended short protocols from the 'big' book.
