特点

使用便利、经严格质量控制的即用型DNA溶液
亚硫酸氢盐转化的DNA，用于对照实验
适用于各种甲基化分析

产品详情

EpiTect Control DNAs是即用型、完全甲基化或非甲基化经亚硫酸氢盐转化的DNA，以及未处理的非甲基化基因组DNA，为甲基化分析设立标准可靠的对照反应。甲基化或未甲基化的亚硫酸氢盐转化DNA储存在EB Buffer（10 mM Tris·Cl）中，是浓度为10 ng/μl的即用型溶液。未转化的非甲基化人类对照DNA也储存在EB Buffer（10 mM Tris·Cl）中，是浓度为50 ng/μl的即用型溶液。

绩效

EpiTect Control DNAs非常适合作为基于探针的real-time PCR甲基化分析的定量标准（参见"") 和用于HRM甲基化分析（参见""）。

原理

EpiTect Control DNA Set包含所有为甲基化分析设立标准可靠的对照反应的对照DNA。例如：在甲基化特异性PCR中，对照反应必须确保PCR探针和引物特异性结合甲基化或非甲基化DNA（参见""）。这些反应需要不同浓度的完全被亚硫酸氢盐转化的对照DNA，而这些DNA全部甲基化或全部非甲基化（参见""和""）。此外，混合的对照DNAs可做为定量标准，用于在HRM和基于探针的甲基化实验中确定甲基化水平。

程序

表观遗传学中标准的工作流程

表观遗传学信息不仅在生物和医学研究领域，尤其肿瘤学研究中是非常重要的，而且对干细胞研究和生物学的发展也至关重要。由于缺乏从有限样本中获得可重复数据的标准方法，分析DNA甲基化变化仍是一个难题。配合其新引进的EpiTect溶液，QIAGEN提供标准的分析前和分析溶液，用于从DNA样本收集、稳定和纯化到亚硫酸氢盐转化和real-time或终点PCR甲基化分析或测序（参见" Standardized workflows in epigenetics"）。

应用

EpiTect Control DNAs适用于各种甲基化分析的对照反应，包括：

评估MSP引物的特异性
作为HRM和MethyLight PCR的定量标准
评估MethyLight PCR引物和探针的特异性
确定亚硫酸氢盐转化反应的效率

辅助数据和图表

EpiTect Methylated Control DNA and EpiTect Unmethylated Control DNA (both pre-bisulfite converted) were mixed to give 100%, 90%, 50%, 10%, and 0% methylated DNA. EpiTect MethyLight Assays for the human PITX2 gene were run in triplicate, using 10 ng of each DNA sample. The results show that EpiTect Control DNA can be used as a methylation standard for the quantification of unknown DNA samples.

FAQ ID -2011

Yes, the EpiTect Control DNA and Control DNA Set can be used as standards in real-time methylation specific quantification. For data, please see our EpiTect MethyLight PCR Product Profile.

FAQ ID -2006

No, the EpiTect PCR Control DNA Set is derived from human DNA. No primers for mouse or rat will bind.

FAQ ID -2008

We have data for DNA converted with EpiTect Bisulfite Kits showing that the bisulfite treated DNA is stable for 3 years at -20°C before use in methylation specific PCR with the EpiTect MSP Kit, or the EpiTect MethyLight PCR Kit.

FAQ ID -2002

The genomic DNA is derived from disease free human whole blood from multiple anonymous donors. The DNA is pooled after purification to yield a mixture of individuals (male/female) and the whole genome is represented. The whole genome is copied stripping the resultant DNA of methylation.

The methylated DNA control is methylated in vitro using SssI methylase. The methylation efficiency is high but not guaranteed to be 100% for every position. Although methylated under optimized conditions for the enzymatic reaction, some positions are as low as 85% as determined by Pyrosequencing. These sites of lower methylation are not random but rules to predict these low positions are undetermined.

QIAGEN checks the consistency of EpiTect Control DNA for methylation and bisulfite conversion using an very sensitive real time MSP-PCR assay. QIAGEN performs several realtime PCR tests to evaluate the bisulfite conversion efficiency as well as the methylation efficiency of the DNAs in the Control DNA Set. We use test systems specific for genomic DNA to detect unconverted DNA or for converted and unmethylated DNA to detect converted but unmethylated DNA, as well as for converted and methylated DNA.
