摘要: 本研究采用间接竞争酶联免疫吸附试验(ELISA)检测黄曲霉毒素B1(aflatoxins B1,AFB1)残留量。将AFB1与蛋白质载体牛血清蛋白(BSA)和卵清白蛋白(OVA)偶联制备了AFB1-BSA和AFB1-OVA偶联物,以AFB1-BSA作为免疫原制备特异性抗体,并成功建立了AFB1残留间接竞争ELISA检测方法及检测试剂盒。试剂盒IC50为128.8 ng/L,检测线性范围为50~1800 ng/L,检测限不超过100 ng/kg;食用油、花生和谷物的平均添加回收率大于71.3%,批内、批间变异系数均小于14.2%。因此,本试剂盒具有操作简便、检测快速、灵敏度高等特点,将在植物性食品中AFB1的残留检测中发挥重要作用。

Abstract: This study was to aim to use ELISA method for rapid screening of the aflatoxins B1(AFB1) residues. Coupled AFB1 to bull serum albumin(BSA) and ovalbumin(OVA) to obtain AFB1-BSA and AFB1-OVA respectively. Specific antibody against AFB1 was prepared with AFB1-BSA and ELISA kit,and had been successfully developed for detecting AFB1 residues. The IC50 of the kit was 128.8 ng/L,linear detection range was 50~1800 ng/L with the lowest detection limit less than 100 ng/kg. The recovery of AFB1 in edible oil,peanut and cereal was more than 71.3%. Coefficient of variation for repeatability tests was less than 14.2%.Therefore,the kit was simple,fast,sensitive,and would be play an important role in AFB1 residues detection in the plant food.

Key words: aflatoxins B1; enzyme-linked immunosorbent assay; kit
