ACE and neoplasm: These included peptides HER-2 (9369), HER-2 (9435) (both recognised by bulk CTL induced by ACE preparations from Ova-1, Ova-2 and Ova-3 primary HER-2/neu-overexpressing tumours), peptide HER-2 (9689), which may be recognised by Ova-2 and Ova-3 induced CTL, and peptides HER-2 (9851) and HER-2 (9665), which were recognised by one of the three bulk CTL.
