Characterization of minor H antigen–specific CTL clones derived by primary in vitro stimulation
CTL clone . | HLA-restricting allele . | Frequency of minor H antigen phenotype, percentage . | Clonal expansion more than 12 days, log10 . | Interferon-γ secretion after stimulation with B-LCL, pg/mL . | Cytotoxicity versus B-LCL, percentage (ET 20:1) . | Cytotoxicity versus fibroblasts, percentage (ET 20:1): recipient . | ||
