摘要:

为得到高效特异的抗卵转铁蛋白多克隆抗体,通过用商品化的卵转铁蛋白(OVT)标品和自制纯化的OVT 免疫新西兰大白兔,用ELISA 及Western blotting 方法检测制备的抗血清效价和特异性。结果表明获得的抗体效价均高达1:819200 以上,抗体特异性强。本实验所建立的方法可成功制备高效特异的抗卵转铁蛋白多克隆抗体,可为进一步研究提供实验材料。

Abstract:

In order to prepare highly specific rabbit anti-ovotransferrin polyclonal antibody, New Zealand rabbits were immunized with commercial ovotransferrin or laboratory-purified ovotransferrin. The titer and specificity of antisera prepared were analyzed by ELISA and Western blotting, respectively. Results showed that all the antisera reached a titer of 1:819200 and exhibited a high specificity. Therefore, target products have been successfully prepared, which might be useful for the further investigations of egg allergy.

Key words: ovotransferrin (OVT), polyclonal antibody, egg allergy
