| 摘 要： | 现有的粪便DNA提取方法通用性不好,DNA纯度不高不适用于白头鹤等水鸟,本研究探索一种改进的硫氰酸胍裂解法。通过线粒体DNA细胞色素b、控制区基因和微卫星DNA的PCR扩增及线粒体DNA控制区序列的测定,经琼脂糖凝胶电泳检测以及测定序列显示,提取的DNA模板纯度高,效果很好,证实改进方法的可靠性、有效性。为其他濒危水鸟的非损伤取样提供了新的材料和方法,为其保护遗传学的研究提供一定的新技术。

| Abstract: | DNA extraction from feces has been complicated by two methodological problems:Most methods are not universally applied and the purity of the DNA is often in adequate to water birds.Previously used methods were found unsuitable for water birds such as Hooded Crane(Grus monacha).In this study we set out to improve the silica-guanidine thiocyanate method for extracting DNA from feces of the Hooded Crane.We isolated and purified DNA using an improved silica-guanidine thiocyanate method.Mitochondrial DNA cytochr... |
