摘要: 利用PCR技术,对转基因大豆中CaMV35S启动子、NOS终止子、CP4-EPSPS和大豆凝集素基因进行了定性检测,并且以大豆凝集素基因为内置标准检测了CaMV35S启动子。采用非变性聚丙烯酰胺凝胶电泳和琼脂糖凝胶电泳对PCR扩增产物进行分析,并对两种电泳进行了比较。聚丙烯酰胺凝胶电泳有利于提高定性PCR筛选方法的准确性。

Abstract: The CaMV35S promoter, NOS terminator, 5-enolpyruvyl-shikimate-3-phosphate synthase gene(cp4-EPSPS) and soybean lectin gene were assayed by qualitative PCR, and the CaMV35S promoter countersigned with soybean lectin by aninternal reaction control was detedcted. Comparing the polyacrylamide gel electrophoresis with agarose gel electrophoresis in the PCR products analysis. The polyacrylamide gel electrophoresis was found to help improve PCR screen accuracy.
