Protein Purification [PDF ebook] 

Protein Purification provides a guide to the major techniques, including non-affinity absorption techniques, affinity procedures, non-absorption techniques and methods for monitoring protein purity. There is an overview of protein strategy and equipment, followed by discussions and examples of each technique and its applications. The basic theory and simple explanations given in Protein Purification make it an ideal handbook for final year undergraduates, and postgraduates, who are conducting research projects. It will also be a useful guide to more experienced researchers who need a good overview of the techniques and products used in protein purification.
