Immunisation with DNApoly2 fails to induce E7/Db or flu/A2-directed immune responses. Pooled splenocytes from A2.1 Kb mice (three per group) immunised twice i.d. with DNApoly2 DNA (a) STMPDV DNA (b) or once with peptide mix + tetanus toxoid + Quil A (c), were restimulated with individual peptides and reacted with EL4.A2 cells pulsed with the cognate peptide (open symbols) or without peptide (filled symbols) in 51Cr-release cytotoxicity assay. Data points are means of triplicate tests ± SD. (Error bars, though plotted, do not appear, because SDs do not exceed symbol size). Data are from one of two experiments with similar results
