食品中苏丹红Ⅰ间接竞争ELISA方法的研究
酶联免疫吸附反应 检测
2015/12/23
建立食品中苏丹红Ⅰ免疫学检测方法。方法 本室自制获得单克隆抗体，优化反应条件，初步建立检测苏丹红Ⅰ的间接竞争ELISA方法，确定抗原包被浓度为1.00 μg/ml，包被温度为4 ℃过夜37 ℃1 h，单抗稀释倍数为1：3200，底物作用时间15 min。结果 检测方法的回归方程和相关系数为：y=-38.541x+131.1，r=0.9841；线性范围为0.053～0.92 μg/L，最低检测浓度为...
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,...
