FIG. 5.
Splenocytes from 2-week-old βAKE mice injected on day 1 with RCASBP/AP-MC1 OVAM257–264(A) virus-producing DF-1 cells (a) or 2-week-old βAKE mice injected on day 1 with RCASBP/AP-αsk OVAM257–264(A) virus-producing DF-1 cells (b) were restimulated in vitro with 0.1 μM SIINFEKL and subsequently assayed for cytolytic activity against control (open boxes) or peptide-pulsed (closed boxes) targets at various E:T ratios (see the text).
