| 摘 要： | 目的:制备特异性识别晚期氧化蛋白产物(Advanced oxidation protein products,AOPP)的多克隆抗体,为研究AOPP的致病机理及与临床病情相关性提供有效工具。方法:用次氯酸氧化家兔血清白蛋白以获得AOPP-RSA,以此为免疫原免疫家兔,亲和层析纯化免疫血清,ELISA鉴定多克隆抗体的效价及特异性,Western blot检测慢性肾脏病(chronic kidney disease,CKD)患者血浆中AOPP,免疫组织化学方法检测肾组织中AOPP分布与定位。结果:获得效价达10-6的抗AOPP免疫血清,纯化抗体可特异地与不同种属来源的氧化修饰白蛋白结合,而与正常白蛋白及糖基化蛋白终产物无交叉反应。该抗体可识别人血浆中的AOPP,可特异地与大鼠CKD模型及各种炎症性CKD患者肾组织成份反应。结论:成功制备了可与不同种属AOPP结合的特异性多克隆抗体,并首次用于检测存在于CKD患者血浆、肾组织及模型动物肾组织中的AOPP,为深入研究AOPP的病理作用及其在组织定位提供了有效工具。
