the reduced levels of pbmc with detectable markers appeared to result from an effect of either ficoll or hypaque on the lymphocytes rather than from loss of lymphocyte subpopulations since higher proportions of cells bearing t4 , t8 , t11 and ia were found when pbmc were isolated with a solution of percoll which yielded a percentage of pbmc as low as that recovered with ficoll-hypaque .
