  • 可浓缩少量RNA至10 μl
  • 可回收不同方法纯化的RNA
  • 15分钟即可获得高品质RNA

产品详情

RNeasy MinElute Cleanup Kit使用基于硅胶膜技术的特制RNeasy MinElute离心柱,可回收并浓缩来自于酶反应体系或其他样本中的RNA。该试剂盒还可用于RNA样本脱盐。可以将至多45 μg的RNA纯化至10 μl的体积中。整个纯化流程可在QIAcube全自动核酸纯化仪上自动完成。

绩效

RNeasy MinElute Cleanup Kit可纯化高品质总RNA,无杂质或酶抑制物,其A 260 /A280比值为1.9–2.1(参见"High-quality RNA") 。相当于少于一个细胞的RNA的量(少至1 pg)也可以被浓缩(参见"Concentration of RNA")。可以纯化大量的RNA(至多45 µg),适用于敏感的分析(参见"Reliable cleanup of RNA")。在下游应用中可采用小量反应体积,确保提高反应效率。该试剂盒可获得高纯度的RNA,可使更多的样本用于反应中,且无抑制作用(参见"Efficient removal of real-time RT-PCR inhibitors")。

原理

RNeasy MinElute Cleanup Kit专为从酶反应(如标记、体外转录)中纯化和浓缩RNA而设计,通过乙醇沉淀和有机提取方法分离RNA,并使RNA样本脱盐,浓缩硅胶膜操作流程制备的RNA(如,PAXgene Blood RNA制备)。RNeasy技术结合异硫氰酸胍裂解和硅胶膜纯化,简化了总RNA纯化技术。

程序

异硫氰酸胍裂解缓冲液和乙醇加至样本中,创造促进RNA选择性结合到RNeasy MinElute膜上的条件。然后将样本上样到RNeasy MinElute离心柱。RNA结合到硅胶膜上,污染物被高效洗去,用水洗脱得到高品质RNA。

同步回收和浓缩酶反应产物或粗RNA制备样本,可在15分钟内完成。相较而言,尤其是从小样本中,耗时的乙醇沉淀浓缩和回收会导致RNA损失。RNeasy MinElute操作流程比真空离心更快,仅离心而无需脱盐和去除其他杂质样本。RNeasy MinElute离心柱独特的设计确保将纯化得到的RNA浓缩至10 µl,用于生物芯片分析和real-time RT-PCR等下游应用。整个纯化流程可在QIAcube全自动核酸纯化仪上全自动进行。

应用

RNeasy MinElute技术纯化得到高品质RNA,适用于各种下游应用,包括:

  • Northern印迹、点印迹和狭缝印迹
  • 终点法RT-PCR
  • 定量real-time RT-PCR
  • 芯片分析
  • Poly A+ RNA筛选
