摘要: 以金黄色葡萄球菌B型肠毒素免疫Balb/c小鼠,待血清效价达到要求后,腹腔注射骨髓瘤细胞,制备抗金黄色葡萄球菌B型肠毒素抗体,并建立快速检测金黄色葡萄球菌B型肠毒素的间接竞争ELISA(ciELISA)方法。经方阵滴定确定B型肠毒素的最佳包被浓度为0.31μg/ml,抗B型肠毒素抗体的稀释度为1:1.2×104,羊抗鼠IgG-HRP的稀释度为1:103。本实验建立的B型肠毒素的间接竞争ELISA检测方法的最低检测量为1ng/ml,线性检测范围为1~103ng/ml,相关系数R2=0.9951,人工污染样品的平均回收率为94.5%。

Abstract: Staphylococcal enterotoxin B was adopted to immune Balb/c mouse.When the mouse serum titer was appropriate,the Balb/c mouse was injected with a non-antibody-secreting myeloma cell SP2/0 for the preparation of antibody.An indirect competitive ELISA for detecting SEB was established in this study.The detection limit of indirect ELISA assay established in this study is 1ng/ml with a detection concentration range of 1~103ng/ml and correlation coefficient R2=0.9951.The recovery of artificially contaminated sample is 94.5%.

Key words: staphylococcal enterotoxin B, anti-SEB antibody, indirect competitive ELISA
