| 摘 要： | 为探索建立基因编辑农产品的检测方法,本研究以猪MSTN基因定点编辑位点为靶标,通过设计PCR-焦磷酸测序引物、优化测序碱基次序、构建标准曲线等步骤,建立基于焦磷酸测序技术的基因编辑产品定性和定量检测方法。结果表明,该方法能够准确检测出MSTN基因第3外显子的AG缺失位点,具备基因分型定性判定和等位基因频率定量检测的功能,从而准确检测样品是否为MSTN基因编辑猪产品,以及样品基因编辑产品的含量。

| Abstract: | In this study,targeted editing sites of MSTN gene were used as object,and a qualitative and quantitative detection method for gene editing products based on pyrosequencing technology was established.The key parameters of the method included PCR and sequencing primers,dispensation order,standard curve and linearity.The results showed that this method could accurately detect the AG deletion site of exon 3 of MSTN gene and had the functions of qualitative genotyping determination and quantitative detection of allele frequency to accurately determine whether the sample was MSTN gene editing pig product or not and the content of gene editing product.This study would provide technical support for the regulation of gene editing products. |
