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, non-therapeutic applications? For example, producing human culture media with specific ingredients for biotechnology 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 technology, this book will prove an invaluable resource.
