Flow cytometric analysis of LAK cells. Spleen cells were incubated in high dose IL-2 for 10 days, and AdLAK cells were harvested for flow cytometric analysis. TAg expression is detected on the x-axis and lymphoid markers on the y-axis. Approximately 10% to 15% of the cells derived from the day 10 adherant LAK preparation are TAg⁺ and are also CD16⁺ and/or NK1.1⁺. Note that the percentage of cells in each compartment is not altered by expression of the transgene.
