Strategies for protein purification.

This discussion unit presents information on classification of proteins according to shape, oligomeric structure, and function. In addition, strategies for purifying different types of proteins are discussed based on their location and associations within the cell. Specifically, critical issues are detailed for extracellular, cytoplasmic, and membrane-associated proteins, as well as for insoluble proteins. Finally, strategies for the purification of both soluble and insoluble (inclusion bodies) recombinantly expressed proteins are provided.
