Abstract
A method of preparing a fibrinogen rich composition is disclosed. One embodiment of the method involves contacting plasma with a hydrogel capable of increasing in mass upon contact with said plasma; maintaining said contact for a period of time sufficient for said hydrogel to absorb a substantial amount of at least the water from said plasma to produce a swollen hydrogel and a fibrinogen rich phase; and separating said fibrinogen rich phase from said swollen hydrogel; whereby said fibrinogen rich composition is produced.
Claims14
A method of preparing a fibrinogen rich composition said method comprising:
- providing a mammalian blood plasma or preparing mammalian blood plasma from whole blood by removal of red blood cells and white blood cells without centrifugation,
- contacting the plasma with a biocompatible hydrogel comprising a polyether,
- maintaining the contact with the plasma to produce a swollen hydrogel and a fibrinogen rich phase, and
- passively separating said fibrinogen rich phase from said swollen hydrogel without centrifugation.
