Taqman定量PCR技术检测转基因大豆中外源基因拷贝数
Detection of Foreign Gene Copies in Transgenic Soybean by Taqman Quantitative PCR Technique
摘要
Abstract
[ Objective ] It is to adopt Taqman quantitative PCR technique to detect the copies of foreign nos terminator in transgenic hybrid soybean. [ Method ] With endogenous reference gene of soybean lectin, and endogenous reference standard of gene complex DNA in non-GMO soybeans, the method of gradient dilution was used to separately calculate Ct value of endogenous reference gene and plasmid DNA and relevance standard curve equation of logarithm of copies, and then to calculate the copies of samples through substituting thus-obtained Ct into standard curve equation. [ Result ] The standard curve equation of endogenous reference gene isy = - 3.422x + 35. 201 , R2 = 0. 998; and the standard curve equation of foreign gene is y = - 3. 348x + 34. 890, R2 = 0.999. Nos terminator and its lower boundary sequences in transgenic soybean is of single copy. [ Conclusion] The study has provided a theoretical basis for determining foreign gene copies in transgenic soybean.关键词
