摘要:

转基因玉米KJ1003是科稷达隆(北京)生物技术有限公司研发的玉米转化体,具有良好的抗虫耐除草剂性能,已获得转基因生物安全证书,产业化前景良好。以KJ1003转化体特异性序列为靶标,通过引物设计、筛选,特异性测试、灵敏度测试、检出限测试、稳健性测试和实验室间验证等,建立了KJ1003转化体特异性普通PCR定性检测方法。结果表明,该方法可扩增获得165 bp特异性片段,检测灵敏度达0.05%,检出限达0.1%,稳健性良好,8家实验室特异性、检出限、重复性和再现性验证结果均达到国家标准要求。构建的方法可为我国转基因作物的检测和安全监管提供科学依据和技术支撑。

Abstract:

The genetically modified maize KJ1003 is a strain developed by Kejidalong (Beijing) Biotechnology Co., Ltd. It shows insect resistance and herbicide tolerance has obtained a genetically modified organism safety certificate and has a good industrialization prospect. This study established a qualitative PCR detection method for maize KJ1003, through primer design, primer screening, specificity test, sensitivity test, detection limit test, stability test, and laboratory validation, with the specific sequence of KJ1003 as the target. Results showed that a 165 bp specific fragment could be amplified, with a detection sensitivity of 0.05% and a limit of detection of 0.1%, and had a good stability. Verification results of specificity, detection limit, repeatability and reproducibility for this method from 8 laboratories all met the national standard requirements. This study provides a scientific basis and technical support for the detection and safety supervision of genetically modified crops in China.

Key words: genetically modified maize, event KJ1003, anti-insect and herbicide-tolerant, event-specific, gel-based PCR, qualitative detection
