    摘要: There is provided a method of concentrating functional biological components within a liquid suspension, the method comprising: providing a system comprising an ultrafiltration/concentration unit (UCU), the UCU comprising a first chamber for receiving therein the liquid suspension. a second chamber for receiving therein the filtrate, and a filter disposed in a fluid path therebetween. the filter comprising pores sizes so as to prevent passage therethrough of the biological components: introducing the liquid suspension into the first chamber: maintaining a pressure in the first chamber being no greater than approximately 2 bar; maintaining a pressure in the second chamber being lower than that of the first chamber: and harvesting the concentrated biological components: wherein a retentate is obtained in which the concentration of the biological components therewithin is increased. relative to the liquid suspension. by a factor of at least fifty. and wherein a majority of the biological components in the retentate are functional.
