产品详情

EZ1 DNA Investigator Kit可从用于人类身份鉴定样本中自动纯化基因组DNA。该试剂盒可配合EZ1 Advanced XL（每批处理1–14个样本）、EZ1 Advanced（每批处理1–6个样本）和BioRobot EZ1（每批处理1–6个样本）工作站使用。纯化过程快速高效，产物DNA在各种下游分析中表现出色，例如定量PCR和STR分析，结果信噪比高。

绩效

更高的纯化效率，用于敏感的下游分析

EZ1 DNA Investigator Kit含有优化的试剂，可自动纯化获得高产量DNA。在STR分析中获得更高的峰值，提高检测灵敏度（参见" Improved performance in STR analysis"）。具有更高的信噪比，确保下游应用中的高灵敏性和优越表现。比较STR分析中的峰高，潜在的DNA的回收率为79%（未显示）。使用TE缓冲液洗脱，结果相似，而且长时间贮存时有更高的稳定性。任何样本的处理过程无遗失（检查任意8个等位基因都有<50的相对荧光单位）。

不同实验方案STR的相对峰高值
实验	试剂盒和卡	方案	洗脱液	相对峰高值	遗漏数

tip dance方式处理固体样本，操作简单

除了标准的微量方案，还可选用全自动tip dance实验方案，移液过程中滤嘴相对工作平台可来回移动。这样可在同一管中直接处理固体样本，如：拭子、组织、血斑或烟头。无需事先离心去除会阻塞滤嘴的固态物质（参见。tip dance实验方案简化了操作步骤，在某些情况下能更有效的提取样本提高DNA的产量（参见" Easy and efficient processing of solid materials with the "tip dance" protocol"）。

经优化的实验方案，更大的样本容量

大体积实验方案可全自动处理的起始样本量多达500 µl。这不仅可以从含有低浓度DNA的稀释样本，如扩散的污渍中高效纯化DNA，而且能够纯化需要用大体积进行彻底裂解的样本。可处理大容量样本（与标准的微量方案有相同的洗脱体积），就可获得更高产量、更高浓度的DNA，在下游应用中有更高的灵敏度（参见" Higher yields of concentrated DNA with the large-volume protocol"）。

有效纯化少量DNA

EZ1 DNA Investigator Kit使用载体RNA，用于提高效率。载体RNA可促进DNA结合到磁珠表面的硅胶上，尤其是含有少量DNA（<100 ng）的样本。公布数据表明载体RNA能够更有效的纯化法医检材样本中的少量DNA，而且对于相同的样本类型可提高DNA产量。载体RNA用于样本裂解也不会影响下游STR分析。

简单的实验设置和操作

使用预设的EZ1 Advanced XL DNA Investigator Card（用于EZ1 Advanced XL）、EZ1 Advanced DNA Investigator Card（用于EZ1 Advanced）和EZ1 DNA Investigator Card（用于BioRobot EZ1）设定纯化方案，十分便利。EZ1 DNA Investigator Kit采用预封装试剂条，减少人工操作的错误和避免缓冲液的污染。通过消除试剂准备和工作站设置时人工操作的失误，以及一个无交叉污染的液体处理，EZ1 Advanced XL、EZ1 Advanced和BioRobot EZ1可确保高度可靠性和标准化。

保证质量

依照QIAGEN's ISO-certified Quality Management System，每批EZ1 DNA Investigator Kit都经过验证，确保始终如一的产品质量。

原理

该试剂盒配合EZ1 Advanced XL、EZ1 Advanced和BioRobot EZ1工作站，采用硅胶膜磁珠技术全自动纯化基因组DNA。磁珠技术无需重复的离心操作，每批可纯化1–14个样本（EZ1 Advanced XL）或1–6个样本（EZ1 Advanced和BioRobot EZ1）。预封装的试剂条和仪器的自动感控锁可降低污染的风险。

程序

将预处理样本加载到工作站，在全自动EZ1 DNA纯化操作后，DNA被一步纯化。洗脱得到的基因组DNA可直接用于各种下游应用。

应用

使用EZ1 DNA Investigator Kit获得的高品质DNA适用于人类身份鉴定，包括：法医检材、血缘关系鉴定、亲子鉴定和受难者身份鉴定，适用如下技术：

STR和SNP基因分型
DNA定量检测
线粒体或染色体DNA测序

FAQ

Operation of the BioRobot EZ1 is so easy that no additional training other than the initial demo is needed. Operating the instrument requires only three major steps:

Insert the appropriate EZ1 Protocol Card, switch on the workstation, and, if necessary, select the appropriate protocol
Follow the instructions on the liquid-crystal display (LCD), which describes where the sample tubes, elution tubes, filter tips, and EZ1 Reagent Cartridges must be loaded and which indicates when to start the protocol run
Collect purified nucleic acids when the protocol run ends

FAQ ID -1239

The Normalization protocol is useful for routine, standardized analyses of reference samples, such as blood or buccal swabs, where sample-to-sample variability can result in widely varying DNA yields. The normalization protocol eliminates the need for yield quantification prior to analysis. It limits DNA yields uniformly to 150-250 ng.

However, please note that the Normalization protocol should not be used if the DNA amount in the sample is very limited. In this case, the Trace protocol on the EZ1 DNA Investigator Card should be used instead.

FAQ ID -1155

Protocols for nucleic acid purification are supplied on pre-programmed EZ1 Protocol Cards. These protocols provide both on-screen instructions for the operator and operating commands for the workstation. The range of kits and protocols for the EZ1 is continuously expanding to allow nucleic acid purification from a wide range of sample types. Please browse our Supplementary Protocol Section to find specialized EZ1 protocols for a large variety of clinical sample types, in addition to the standard sample types covered in our EZ1 handbooks.

FAQ ID -1241

Loading of sample tubes, elution tubes, filter-tips, and Reagent Cartridges onto the worktable of the BioRobot EZ1 is intuitive, easy and quick. Details about worktable setup are provided with each new protocol, and are also displayed in the liquid-crystal display (LCD) of the control panel when you start setup of the worktable.

FAQ ID -1243

Yes, the Tip Dance protocol of the EZ1 DNA Investigator Card can cope with solid matrix that remains in the sample tube. However, very fluffy/diffuse materials (e.g. paper tissues) can clog the tips.

FAQ ID -1153

No, the EZ1 DNA Forensic Card cannot be used with the EZ1 DNA Investigator Kit.

FAQ ID -1151

No, prefilled Reagent Cartridges can be loaded onto the BioRobot EZ1 with their seals. During operation of the instrument, the piercing unit, a row of 6 metal spikes located behind the tip adapters, will puncture the foil of the cartridges, thereby exposing the reagents.

FAQ ID -1240

Bisulfite conversion of unmethylated cytosines into uracils with the EpiTect Bisulfite Kit works on DNA irrespective of the source organism. The DNA template needs to be of high purity for efficient conversion. We recommend to use genomic DNA extracted with our DNA isolation kits for clinical or animal and plant samples as a template for the EpiTect Bisulfite Kit.

FAQ ID -1209

No extra accessories need to be purchased for the BioRobot EZ1, as sample and elution tubes, as well as tips and tip holders are included with each EZ1 DNA or RNA isolation kit.
