以SDS作为解离剂,采用常规SDS法、改进的SDS法及SDS高盐低pH法分离提取蔓茎堇菜基因组DNA.比较3种方法的提取效果,结果表明:常规SDS法DNA得率高但完整性及纯度较差;改进的SD S法D N A质量好但得率相对较低;只有SDS高盐低pH法是最为理想...以SDS作为解离剂,采用常规SDS法、改进的SDS法及SDS高盐低pH法分离提取蔓茎堇菜基因组DNA.比较3种方法的提取效果,结果表明:常规SDS法DNA得率高但完整性及纯度较差;改进的SD S法D N A质量好但得率相对较低;只有SDS高盐低pH法是最为理想的提取方法,不同组织提取的DNA相对分子质量均大于48kb,260nm/280nm光密度比值在1.7~1.9之间,产率为479.0~543.9μg/g,所得DNA可直接用于限制性内切酶酶切,并适于进行RAPD分析.展开更多
