一般說明
卵清蛋白（323-339）是由B细胞表位环绕的蛋清蛋白，被特异性IgE抗体结合。除此之外，它还含有CD4+ T细胞表位。
该肽是卵清蛋白的第II类主要MHC限制性T细胞表位，用于研究免疫性过敏反应，如哮喘、食物过敏等。
應用
卵清蛋白（323-339）（鸡，日本鹌鹑）已被用于诱导小鼠过敏性哮喘。
生化／生理作用
卵清蛋白（OVA）肽323-339在隔离的BALB/c小鼠体内介导25-35％的T细胞对完整OVA的反应。OVA 323-339被广泛用于测定第II类主要组织相容性复合体（MHC）-肽结合特征和T细胞活化特征。
在两个功能不同的辅助因子的帮助下，卵清蛋白（323-339）肽可与组织相容性复杂的II类I-A（d）蛋白结合。
