- 摘要:
- 以大豆球蛋白特异性多克隆抗体为一抗,辣根过氧化酶标记抗兔IgG( HPR) 为酶标二抗,TMB 为底物,建立一种检测大豆球蛋白直接ELISA 方法。应用该方法对在吉林省部分地区收集的25 个样本进行初步检测,并与竞争ELISA 方法进行对比,每个样品进行6 个重复,结果显示,约64%的样本使用直接ELISA 法的蛋白检出显著高于竞争ELISA 法,且标准差的符合率达到72%以上。本试验建立的直接ELISA 方法具有较高的敏感性和特异性,适于食品及饲料行业中过敏蛋白的批量检测。
- Abstract:
- The present study presents a direct enzyme-linked immunosorbent assay( ELISA) that allows for the detection oftrace amount of glycinin in soybean. In this assay,rabbit anti-glycinin polyclonal antibody( Pab) was used as primary antibodyand goat anti-mouse igG-horseradish peroxidae( HRP) was used as secondary antibody. Twenty-five samples collected in partsof Jilin province were preliminary tested by this detection method and compared with competitive ELISA method. Resultsshowed amounts of glycinin in about 64% samples detected by the dcELISA were significantly higher than that detected bycompetitive ELISA and the coincidence rate of the standard deviation( SD) was more than 72%. The method showed a goodsensitivity and specificity and was suitable for quick and large quantitative detection of glycinin in food and feed industry.
