Performance

DNeasy Plant Maxi Kit可快速高效的纯化高品质DNA,可以从不同种类的植物和组织样本中进行纯化,包括较难处理的样本来源(参见下表)。样本可以是新鲜、冷冻或者风干的。优化的DNeasy Plant操作流程与QIAshredder Maxi离心柱结合使用,独特的过滤和匀质柱,能够有效的去除细胞碎片并且优化裂解后的样本处理流程。

幼叶或针叶(以及其他组织,如上)收集并立即速冻。使用DNeasy Plant Mini Kit进行DNA提取。1山毛榉、2干叶、3愈伤组织、4年植物上的叶子、5胚乳、6富含碳水化合物的老树叶、7芽。包括真菌在内的其他物种的DNA提取的详细信息,请联系QIAGEN公司的技术支持或当地的经销商。

常规产量为3–30 µg,样本量达100 mg湿重,洗脱体积为50–400 µl。DNA产量因种类和组织的不同而不同,取决于基因组大小、倍体、细胞数量和组织样本的年龄。较低和较高的范围值分别对应拟南芥和小麦。

DNeasy Plant操作流程制备纯核酸,无多糖和其他使用常规方法纯化产生的次生代谢产物。这些杂质可能会干扰分光读数并抑制酶反应。DNeasy纯化的DNA的吸光度扫描在260 nm处显示对称峰(参见"DNA purity from pine needles"),证明DNA无酶抑制剂等杂质。DNeasy纯化的DNA最长为40 kb(参见"Pure DNA")。纯化的DNA可用于多种应用(参见"PCR analysis"和"RAPD analysis")。

Principle

DNeasy Plant Kits使用先进的硅胶膜技术和简单的离心操作流程从植物组织和细胞或者真菌中提取高纯度的细胞总DNA。DNeasy技术取代繁琐的DNA提取操作流程,如十六烷基三甲基溴化铵(CTAB)、苯酚或者氯仿萃取。使用DNeasy操作流程不需要乙醇沉淀,纯化的DNA可以直接使用。DNeasy样本制备技术已经过认证。

Procedure

首先对样本进行机械搅拌,然后进行化学裂解(参见"DNeasy Plant and DNeasy 96 Plant procedures")。在裂解过程中,RNA被RNAase消化去除。细胞碎片、沉淀的蛋白质和多糖都被去除,并且样本通过QIAshredder Maxi离心柱并离心实现匀浆。调节缓冲溶液条件,并将裂解产物上样到DNeasy Plant Maxi离心柱中。在短暂的离心过程中,DNA选择性结合到硅胶膜上,污染物通过。余下的污染物和酶抑制剂经过一或者两步高效的洗涤步骤去除。然后,用水或者低盐缓冲溶液将纯化的DNA洗脱,待用。
