植物DNA提取原理
通常采用機械研磨的方法破碎植物的組織和細胞,由于植物細胞勻漿含有多種酶類(尤其是氧化酶類)對DNA的抽提產生不利的影響,在抽提緩沖液中需加入抗氧化劑或強還原劑(如巰基乙醇)以降低這些酶類的活性。在液氮中研磨,材料易于破碎,并減少研磨過程中各種酶類的作用。十二烷基肌酸鈉(sarkosyl)、十六烷基三

植物DNA提取中怎樣檢測提取到DNA質量
第一種方法是測量260/280的比例,判斷是否有蛋白質的污染。在260nm和280nm處測定DNA溶液的光吸收,A260與A280之比應在1.75-1.80之間。低于此值表明制備物中殘留蛋白質成分較高或含有酚,高于此值表明有RNA的殘留。第二種方法是凝膠電泳分析,看有無斷裂降解。影響DNA提取質量的
