Quantitative Detection of Genetically Modified Soybean BPS-CV127-9
摘要
Abstract
A quantitative method to detect the transgenic soybean BPS-CV-127-9 by using real-time PCR technique based on fluorescence dye SYBR Green I was investigated in this study. The endogenous lectin gene and the 5' flanking sequences of BPS-CV-127-9 were amplified through the specific primers,and the transgenic content was then calculated according to the standard curve equation. Meanwhile the specificity of PCR amplification was analyzed by corresponding melting curves. The results showed that the standard curves of lectin and the 5' flanking sequences of BPS-CV-127-9 genes have good linear relationship, and their R values were 0. 999 and 0. 998, respectively. The coefficient of variance was 1. 50%-18. 51% and standard deviation was 0.02-0.07. Four mixed samples with genetically modified contents of BPS-CV-127-9 was 0.05% ,0.1% ,0.5% and 1% respectively were detected,and the detection results agreed well with actual value. In conclusion,this method was fast, sensitive, simple, accurate, specific and of high throughput, and could be used to detect transgenic soybean BPS-CV-127-9 quantificationally.关键词
