ZR Plant RNA MiniPrep™---植物基因组RNA小量提取试剂盒
About ZR Plant RNA MiniPrep™
The ZR Plant RNA MiniPrep™ provides for rapid isolation of RNA from various plant samples (e.g. leaves, stems, buds, flowers, fruit, seeds etc.). For purification of total RNA including small RNAs (~50 µg), the ZR Plant RNA MiniPrep™ features a specially formulated RNA Lysis Buffer. The Zymo-Spin™ IIIC Column allows for high-capacity DNA elimination and the subsequent Zymo-Spin™ IIC Column efficiently adsorbs total RNA.
The RNA is washed and then eluted with DNase/RNase-Free Water. For inhibitor removal, the eluted RNA can be treated by running the sample through the Zymo-Spin™ IV-HRC Spin Filters. The RNA is suitable for use in various subsequent procedures including RT-PCR.
The entire RNA isolation procedure typically takes about 10 minutes.
| Format |
Bead beating, spin column |
| Equipment |
Microcentrifuge, vortex and/or cell disrupter/pulverizer (optional). |
| Sample Sources |
Leaves, stems, buds, flowers, fruit, seeds, etc. |
| RNA Purity |
High quality total RNA (A260/A280 > 1.8, A260/A230 > 1.8) is recovered. In general, traces of DNA may be present in the eluted RNA fraction. Complete removal of DNA can be accomplished by performing an in-column DNase I digestion. |
| RNA Recovery |
RNA can be eluted into small volumes, ≥25 µl, allowing for a highly concentrated sample. Maximum RNA binding capacity of the provided column is ~50 µg. |
| Compatibility |
Compatible with samples stored in RNAlater ™. |
| RNA Storage |
RNA is eluted with RNase-free water and can be stored at ≤-70 ºC. The addition of RNase inhibitors is optional but highly recommended for prolonged storage. |
|
Isolation of total RNA from 10 mg of a fresh leaf material (Nicotiana sp.) using the ZR Plant RNA MiniPrep™. Leaves were minced then processed using a FastPrep®-24 instrument (MP Biomedicals). Samples 1 and 2 were loaded in 2x and 1x volume aliquots, respectively, and resolved in a 1% (w/v) nondenaturing agarose gel. RNA Millenium™ Markers (Ambion) were used as size standards
|
|
Nicotiana sp. leaf samples were spiked with humic acid (Sigma) at a final Ab230nm = 0.2. Total RNA was isolated with the ZR Plant RNA MiniPrep™ with and without the use of theZymo-Spin™ IV-HRC Spin Filter. RT-PCR performed with a LightCycler® 480 (Roche) showed an increase in fluorescence signal and detected an early amplification initiation for theZymo-Spin™ IV-HRC treated samples compared to the non-treated samples (cp = [30 vs. 31], respectively).
|
Quick, 10 minute isolation of inhibitor-free total RNA (~50 µg) from a wide variety of plant samples using ultra-high density BashingBeads™ and Zymo-Spin™ column technologies.
High-quality RNA eluted in ≥25 µl is ready for reverse transcription, microarray, sequencing, etc.

关于5-hmC
5-hmC是近年来在动物组织中发现的，由胞嘧啶修饰而来。5-hmC在表观遗传学上的功能可能与5-甲基化胞嘧啶(5-mC)不同。尽管到现在为止还不确知其功能，有研究者猜测它在调控基因的表达与关闭过程中起着重要的作用。5-mC的发现让我们不得不重新评估DNA甲基信息，也不得不监测人类的健康组织和病理组织之间5-mC相对分布的差异。在EPI公司的MethylFlash技术之前，我们还没有发现任何直接的常规方法来检测5- hmC,以及区分5-hmC和5-mC
5-hmC 和 5-mC的区别
时下常用的DNA甲基化分析方法包括限制内切酶酶切和亚硫酸氢盐或MeDIP介导的MS-PCR和测序，这些技术都不适合用来检测5-hmC，因为它与5-mC事实上很难用这类方法区分开来。为了解决这个问题，EPIk研制了MethylFlash羟甲基化DNA定量试剂盒(荧光法)。本试剂盒提供了一种很经济的方法来检测5-羟甲基化胞嘧啶，并且区分5-hmC, 5-mC, 和 C，使得研究者能够重新评估他们的DNA甲基化信息，也能够在新样品中寻找DNA羟甲基化。
