摘要:
本研究利用竞争洗脱法淘选与Cry3Bb毒素具有亲和力的特异性短肽,以此建立间接竞争酶联免疫吸附检测方法(IC-ELISA)。经过4轮淘选、富集,获得与靶蛋白具有较高亲和力的B10克隆(ACIHSPTALCGGG)。所建立的检测方法稳定性较好,变异系数在5%以内;线性检测范围为 0.03~2995 μg/ml,线性回归方程为 (Y=20044x+50407,R2=0.983 4),检测限为0.009 6 μg/ml,在玉米样品中提取回收率为 92.26%~10122%。本研究所建立的ELISA 检测方法为粮食中Cry3Bb蛋白的定量检测提供了有效的手段,在转基因产品的检验检疫中有较高的应用价值。
Abstract:
This study aimed to develop a quantitative indirect competitive enzyme-linked immunosorbent assay (IC-ELISA) for detection of Cry3Bb protein in corn. A Ph.D.-C7C phage display peptide library was used to screen peptides specifically binding Cry3Bb. An phage clone, B10(ACIHSPTALCGGG), showed higher affinity and specificity to Cry3Bb in vitro compared to other clones. The newly developed ELISA exhibited good stability with the coefficient of variation less than 5%. In the concentration range of 0.03-2995 μg/ml, the linear equation Y=20044x+50407,R2=0.983 4, was regressed with the detection limit of 0.009 6 μg/ml. The recoveries of Cry3Bb in corn extract ranged from 92.26% to 10122%. The established IC-ELISA provides an effective way to quantitatively detect Cry3Bb protein in corn.
