Shape your heart to front the hour, but dream not that the hour will
lost. Alfred Tennyson Locksley Hall Sixty YeO!, After Numerous advances
in the life sciences have necessitated the need to develop gentle, quick
and economical methods for separation of proteins/enzymes. Affmity-based
separations, with their high selectivity, have thus come to be used more
frequently. In the beginning, we just had atrmity chromatography. Today
we have several strategies that employ atrmity interactions for separa-
tion and analysis. This book is an attempt to provide a short
introduction and illustrative protocols for some important and current
affinity-based approaches inthe area ofdownstream
processingofenzymes/proteins. Today, people from a variety of
disciplines have to purify proteins. It is hoped that this book will
provide some quick insight into the various available options and guide
even a novice (in the area ofprotein separation) to obtain his/her
target protein at the level of purity that he/she desires.
