Improved granulocyte collection from normal donors by combination of continuous-flow centrifugation and filtration leukapheresis. 1975

J P Gmür, and J Deluigi, and P W Straub

A total of 30 leukaphereses were performed with the Aminco Cellseparator on 27 healthy donots. Pretreatment by steroids and addition of fluid gelatin to the input line was performed in all runs. The combination of continuous flow centrifugation and filtration leukapheresis (CFC-FL) in nine of the 30 runs resulted in a highly significant increase of the yield to a mean of 59.6 X 1o(9) granulocytes as compared with a mean of 30.8 X 10(9) granulocytes obtained with conventional CFC. This significance is valid for the total yield of granulocytes, the yield per hour of run, or per liter of blood processed. No adverse reaction occurred.

D002498 Centrifugation Process of using a rotating machine to generate centrifugal force to separate substances of different densities, remove moisture, or simulate gravitational effects. It employs a large motor-driven apparatus with a long arm, at the end of which human and animal subjects, biological specimens, or equipment can be revolved and rotated at various speeds to study gravitational effects.

D005374 Filtration A process of separating particulate matter from a fluid, such as air or a liquid, by passing the fluid carrier through a medium that will not pass the particulates. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) Filtrations
