OVA peptide mainly exists in egg white, it is a class I (Kb)-restricted peptide epitope of ovalbumin presented by the class I MHC (major histocompatibility complex) molecule, H-2Kb (class I genes of the mouse MHC). OVA peptide has been widely studied in allergy research.
OVA peptide with bone marrow-generated DC pulse are potent inducers of OVA-specific CTL responses in vivo, compared with splenocytes or RMA-S cells pulsed with OVA peptide, or compared with immunization with free OVA peptide mixed with adjuvant[2].
