大豆及豆制品中DNA提取方法初探

Methods for DNA Extraction from Soybean and Bean - made - foods

为了满足转基因食品标签制管理的需要,必须从食品中提取DNA,并运用PCR方法检测外源基因的有无。本文初探了大豆及常见豆制品中DNA的提取方法,为转基因食品的PCR检测打下了基础。

In order to meet the requirement of the GMO labeling provisions, it is necessary to extract DN A from foods and confirm the existence of transgenic gene by PCR. We discussed three methods for DNA extraction from soybean and bean - made - foods, which could be applied in PCR screening of GMO.
