Relative surface expression of IL-2Rα, β and γ subunits on Kit 225 K6 T cells

	Subunit	Number of copies (×103)*
IL-2Rα	(Tac, p55)	96 ± 12†
IL-2Rβ	(p70–75)	11 ± 5
IL-2Rγ	(p64)	8 ± 4

^*The number of IL-2R subunits per cell was determined from the mean fluorescence intensities of flow cytometric histograms of cells labeled to saturation with fluorescently conjugated mAbs as described in Materials and Methods. 

^†Data represent mean ± SEM of at least three independent measurements.
