Phenotypic characterization of IL-2-activated murine primary NK cells. The surface expression of various NK cell markers (a) NK1.1 (b) DX5 and (c) CD11b, activatory receptors (d) CD27, (e) TRAIL, (f) CD16/32, (g) NKG2D, activatory and inhibitory receptors (h NKG2A/C/E, i CD94, j KLRG1, k Ly49D, l 2B4), as well as activation status markers (m) CD69 and (n) B220, was analyzed by flow cytometry following staining with specific antibodies (solid line). Isotype control-stained NK cells were used as a control. Data shown are representative of three independent experiments
