Bovine blood mononuclear cells were separated into 2 fractions by use of centrifugl elutriation. Total recovery, as well as recovery of each fraction, was greater than that obtained by use of Ficoll-sodium diatrizoate separation. The lymphocyte fraction contained less than 1% granulocytes, and the granulocyte fraction contained only 7% lymphocyte contamination. The technique was reproducible and results proved to be comparable with those of Ficoll-sodium diatrizoate density-gradient centrifugation; furthermore, the method is considerably cheaper and less time-consuming for processing large volumes of blood. Viability of cells separated by elutriation always was greater than 98%, whereas viability of cells separated by Ficoll-sodium diatrizoate was greater than 95%. Also, mitogen activation of lymphocytes separated by elutriation was superior to that of lymphocytes separated by Ficoll-sodium diatrizoate centrifugation.
