More than 70% of leucocytes or lymphocytes present in packed red cells were separated and recovered by cotton-wool (Gossypium barbadense) filtration. Adhering leucocytes was recovered from an Imugard filter by a plasma-containing solution with an inverted tapping. Cell viability tests as assessed by the Trypan Blue dye exclusion and phytohemagglutinin-induced transformation revealed that the recovered lymphocytes were viable.
