Snippet: Induction of Primary CTLs. PBMCs from HLA-A2-positive healthy donors and HCV patients were isolated on Ficoll-Paque density gradients and washed three times in PBS containing 10% FCS-medium. 4 Ï« 10 6 PBMCs were incubated with synthetic peptide (10 g/ml; Chiron Mimotopes) in RPMI 1640 medium supplemented with l -glutamine (2 mM), penicillin (50 U/ml), streptomycin (50 g/ml), and Hepes (5 mM) containing 10% (vol/vol) heat-inactivated human AB seru.....
Document: Induction of Primary CTLs. PBMCs from HLA-A2-positive healthy donors and HCV patients were isolated on Ficoll-Paque density gradients and washed three times in PBS containing 10% FCS-medium. 4 Ï« 10 6 PBMCs were incubated with synthetic peptide (10 g/ml; Chiron Mimotopes) in RPMI 1640 medium supplemented with l -glutamine (2 mM), penicillin (50 U/ml), streptomycin (50 g/ml), and Hepes (5 mM) containing 10% (vol/vol) heat-inactivated human AB serum (AB-medium) for 1 h, washed once in PBS containing 10% FCS-medium, and then plated in 24-well plates at 4 Ï« 10 6 cells/well in AB-medium. On day 3 and weekly thereafter, 1 ml of complete medium supplemented with rIL-2 (20 U/ml; EuroCetus B.V.) was added to each well. On day 7 and weekly thereafter, the cultures were restimulated with 10 6 peptide-pulsed, irradiated (7,400 rads) autologous feeder cells in 1 ml of AB-medium containing rIL-2 (20 U/ml). The cultured PBMCs were tested for CTL activity against different peptides on day 35 .
