Ovalbumin (OVA) peptide, primarily found in egg white, is a class I (Kb)-restricted peptide epitope presented by H-2Kb, the mouse MHC (major histocompatibility complex) class I gene product. It has garnered significant attention in the field of allergy research [1] [2].

OVA多肽与骨髓来源的DC脉冲共同处理能显著诱导体内OVA特异性CTL反应，与脾细胞或RMA-S细胞用OVA多肽脉冲处理，或与自由OVA多肽混合佐剂免疫的方式相比较[2]。
