There are today five major proteins in plasma fractioning. In the near future, other fractions could also be used as therapeutic agents. But perhaps they could be used for alternative, n-therapeutic applications? For example, producing human culture media with specific ingredients for biotechlogy research might also be of use. Whatever the future may hold, there is one essential question: in today's world of cellular and genetic engineering, are extracted therapeutic proteins still of any relevance? For a clear and up-to-date view of recent developments in blood-protein-separation techlogy, this book will prove an invaluable resource.
