ABSTRACT
This chapter focuses on the biological process is often prolonged, because the time to develop biological process can be lengthy. The complexity of most protein purification processes gives added importance to strategy considerations in the development of these processes. For process development work at the laboratory scale, a good starting point is a typical protein chemistry laboratory. Bringing a new protein to market is often extremely complex, involving a number of professionals from different disciplines who are involved in tasks that frequently must occur simultaneously. The creation of a processing scheme to purify a protein is called process synthesis. A common tendency of those working in protein purification is to follow only the main product stream in terms of specific activity and total protein concentration. A better approach is to analyze each stream in a given step for the desired protein.
