2.2 TRANSFORMATION OF PLASMA INTO PLASMA<br />

DERIVATIVES<br />

2.2.1 Quick overview of fractionation process<br />

S<strong>in</strong>ce the early 1940s the method of manufactur<strong>in</strong>g plasma, <strong>in</strong>itially developed by Pr<br />

Edw<strong>in</strong> J. Cohn, has been <strong>in</strong>fluenced by multiple factors, which over the years have<br />

forced the <strong>in</strong>dustry to adapt production <strong>in</strong> such a way that the optimal use of plasma – a<br />

human source - rema<strong>in</strong>s to be the lead<strong>in</strong>g objective. As already mentioned above,<br />

human plasma, <strong>is</strong> a unique biological material. Plasma fractionation, a “crack<strong>in</strong>g” process<br />

(cf. petroleum “crack<strong>in</strong>g”) used to prepare therapeutic prote<strong>in</strong>s, <strong>is</strong> and rema<strong>in</strong>s a<br />

complex process. Human plasma derived prote<strong>in</strong> products have unique character<strong>is</strong>tics<br />

l<strong>in</strong>ked to the orig<strong>in</strong> of the start<strong>in</strong>g raw material. Human plasma exhibits a complex<br />

biochemical nature due to its high prote<strong>in</strong> content, close to 60 g per litre, and to the<br />

diversity of its prote<strong>in</strong> components.<br />
