特点

  • 集样本收集、稳定和纯化于一体

  • 在18–25°C条件下RNA稳定3天
  • -20°C或-70°C条件下至少稳定50个月

产品详情

PAXgene Blood miRNA System包含PAXgene Blood miRNA Kit,用于纯化大于18 nt的总RNA(含miRNA);以及用于血液收集、稳定和运输的PAXgene Blood RNA Tubes(BD提供,货号762165)。该试剂盒基于硅胶膜技术,以离心柱方式纯化RNA。纯化可使用小离心机手工完成,或者在QIAcube全自动核酸纯化仪上自动进行。配合PAXgene Blood RNA Tubes,系统提供了一个样本分析前处理的标准方案,包括从收集、稳定到RNA纯化的全过程(包括miRNA),适用于分子分析。

绩效

血液样本在PAXgene Blood RNA Tubes中收集后可安全保存,或转移到15–25°C下保存72小时,在2–8°C下保存5天,在–20°C或–70°C下保存至少50个月,而不会发生明显的RNA降解或转录水平的变化。使用PAXgene Blood miRNA Kit从稳定的血液样本中纯化大于18个核苷酸的总RNA,包括mRNA和miRNA等小RNAs(参见" High yields of small RNA species")。使用QIAGEN miScript PCR System(参见" Analysis of miRNA species")或其他real-time RT-PCR系统可分析miRNA种类。

原理

血液样本收集在PAXgene Blood RNA Tubes中。管中含有的试剂可裂解血液细胞并立即稳定胞内RNA,保护基因表达谱。RNA稳定对于可靠的下游基因表达分析非常重要。收集血液后如果没有立即稳定,就会造成RNA降解、转录本的上调或下调。

程序

使用PAXgene Blood miRNA Kit,运用经验证的PAXgene硅胶膜技术可从稳定的血液样本中纯化大于18个核苷酸的RNA(包括miRNA)。可手工操作完成纯化或在QIAcube全自动核酸纯化仪上自动进行(参见"The QIAcube")。

FAQ

Where can I find additional information for PreAnalytiX PAXgene products?
You can find additional information relating to the PreAnalytiX PAXgene products on the PreAnalytiX website .
FAQ ID - 3515
Can the PAXgene Blood miRNA System be used for diagnostic or prognostic procedures?
No. The PAXgene Blood miRNA Kit is ‘For Research Use Only’. Not for use in diagnostic procedures. No claim or representation is intended to provide information for the diagnosis, prevention, or treatment of a disease.
FAQ ID -2494
What are the expected yields of RNA from PAXgene Blood RNA Tubes isolated with the PAXgene Blood miRNA kit?
Typical yields of RNA isolated from 2.5 ml healthy, human, whole blood (4.8 x 106 –1.1 x 107 leukocytes/ml) are ≥3 μg for >95% of the samples processed (Refer to Technical Note) . Since yields are highly donor-dependent, individual yields may vary.
FAQ ID - 3481
Is it possible to isolate genomic DNA or viral nucleic acids with PAXgene Blood miRNA protocol?
No. The PAXgene Blood RNA System has been optimized for cellular RNA only. PreAnalytiX offers a dedicated system for collection and isolation of genomic DNA from human whole blood (see PAXgene Blood DNA System) .
FAQ ID - 3483
What can I use to isolate RNA smaller than 200 nucleotides?

For the isolation of microRNA (miRNA) specifically, we have developed the miRNeasy Mini Kit and the miRNeasy 96 Kit for isolation from cells and tissues.   We also have the PAXgene Blood miRNA and Tissue miRNA kits for isolation from blood stored in PAXgene Blood RNA tubes and PAXgene Tissue Containers, respectively.  Other miRNA isolation supplementary protocols can also be found by searching our comprehensive protocols at http://www.qiagen.com/literature/default.aspx?WT.svl=m.

FAQ ID -115
What is the maximum number of samples for the QIAcube variant of the PAXgene Blood miRNA protocol for a single run?

Up to 12 samples can be processed in a single run.

FAQ ID - 3482
How great is the enrichment of miRNA when using the dedicated PAXgene Blood miRNA Kit compared to the PAXgene Blood RNA Kit?

If the PAXgene Blood miRNA Kit is used, an enrichment of small RNAs as part of the total RNA is achieved. The enrichment may vary between different miRNA species and samples, but on average an enrichment of about three or more CT-values can be expected.

FAQ ID -2495
Do eluates generated with the PAXgene Blood miRNA Kit contain residual genomic DNA?
Typically, the amount of genomic DNA (gDNA) in eluates of the PAXgene Blood miRNA Kit is very low as long as the kit is stored and used according to the instructions of the PAXgene Blood miRNA Kit Handbook. For downstream applications that are especially sensitive to gDNA contamination, a specialized protocol for the QIAcube helps reduce gDNA content further and can be downloaded from the QIAcube product page.
FAQ ID - 3637
Which sample types can be processed using the PAXgene Blood miRNA protocols?
2.5 ml whole human blood collected in PAXgene Blood RNA Tubes
FAQ ID - 3478
Do you have stability data for RNA isolated with PAXgene miRNA Kit?
Stability data are not yet available, but a stability study was started.
FAQ ID - 3480
How many samples can be processed with the PAXgene Blood miRNA Kit?
The kit can be used for 50 RNA isolations.
FAQ ID - 3477
Do the samples require pretreatment before starting the manual protocol or before loading onto the QIAcube instrument?
Yes. Samples have to be incubated at least 2 h at room temperature (18-22°C). Incubation of the PAXgene Blood RNA Tube overnight may increase yields slightly in some cases. Room temperature storage for up to three days has no effect on the RNA profile. During the preparation of the RNA the manual pretreatment consist of a centrifugation and a pellet resuspenion step (see the PAXgene Blood miRNA Handbook ).
