a). A portion of a scanned cDNA microarray showing the differential expression of NKG2 C. The cDNA fragment spotted on position H11 correspond to NKG2 C. (I) Hybridization pattern for LGL patient. (II). Hybridization pattern for control. b). Northern Blot showing the expression of NKG2 family members. The probe used was the same as the one spotted on the microarray. Lane LGL = total RNA isolated from LGL leukemia patients (LGL). Lanes N = total RNA isolated from normal healthy controls.
