根据《中国食品科学技术学会团体标准工作管理办法》等规定，我学会组织起草了《葡萄球菌肠毒素测定 ELISA试剂盒法（征求意见稿）》团体标准。现公开征求意见，请于2023年8月11日前将相关意见反馈学会秘书处。
本文采用活性酯法和N,N-羰基二咪唑法分别合成了酸性红73的人工抗原,方阵滴定实验表明活性酯法所得兔抗酸性红73的Ig G更适合用于后继实验,以此为基础建立了一种虾仁中酸性红73的间接ELISA检测方法并对反应条件进行了优化。优化后,该方法的半数抑制浓度(IC50)为45.39μg/L,检测限(LOD)为5.64μg/L。交叉反应实验结果表明除苏丹红3号(0.15%)外与番红花红、苯酚红、刚果红、...
间接竞争ELISA法检测坚果类过敏原特异性研究
坚果 过敏原 ELISA 棋盘法
2016/5/19
以腰果蛋白为过敏抗原,腰果蛋白致敏的阳性小鼠血清作为一抗,羊抗鼠Ig E-HRP为二抗建立双抗体间接酶联免疫吸附实验(ELISA)体系,通过棋盘法确定腰果蛋白最佳反应条件工作浓度为15.92μg/m L,最佳一抗稀释度均为1∶400,最佳酶标二抗的稀释度为1∶1000,腰果蛋白浓度为1.99μg/m L。并用该方法分别对腰果、核桃、榛子、开心果、板栗、杏仁等六种坚果进行检测分析,未发现有交叉反应,...
