植物DNA提取原理

通常采用机械研磨的方法破碎植物的组织和细胞,由于植物细胞匀浆含有多种酶类(尤其是氧化酶类)对DNA的抽提产生不利的影响,在抽提缓冲液中需加入抗氧化剂或强还原剂(如巯基乙醇)以降低这些酶类的活性。在液氮中研磨,材料易于破碎,并减少研磨过程中各种酶类的作用。十二烷基肌酸钠(sarkosyl)、十六烷基三

植物DNA提取中怎样检测提取到DNA质量

第一种方法是测量260/280的比例,判断是否有蛋白质的污染。在260nm和280nm处测定DNA溶液的光吸收,A260与A280之比应在1.75-1.80之间。低于此值表明制备物中残留蛋白质成分较高或含有酚,高于此值表明有RNA的残留。第二种方法是凝胶电泳分析,看有无断裂降解。影响DNA提取质量的
