Experimental Protocol


Total RNA was isolated from magnetic-activated cell sorter (MACS)-freshly purified hCMV-stimulated CD69+, hCMV-stimulated CD69- and unstimulated monoclonal CD4+ T-LGL lymphocytes from PB samples from four TCRVbeta+/CD4+ T-LGL lymphocytosis patients (purity of ≥98%). Briefly, 100 ng of total RNA from each of the 12 purified cell fractions was amplified and labeled using the GeneChip two cycle cDNA synthesis kit and the GeneChip IVT labeling kit (Affymetrix Inc., Santa Clara, CA), respectively. Then it was hybridized to the Human Genome U133 Plus 2.0 Array (Affymetrix). In parallel, total RNA was also isolated from highly purified (≥ 98% purity) hCMV-stimulated (specific) CD69+ CD4+ T-lymphocytes isolated from PB samples from hCMV-seropositive healthy donors (n=5, mean age of 36 years) using a FACSAria flow cytometer (BDB). To get pure and highly concentrated RNA, the silica membrane technology NucleoSpin® RNA XS (Macherey-Nagel, Düren, Germany) was used. Total RNA was then amplified, labeled and hybridized to the Human Genome U133 Plus 2.0 Array (Affymetrix) as described above.
