Product Details

The EpiTect Whole Bisulfitome Kit provides DNA polymerase, buffers, and reagents for amplification of the entire bisulfite converted genome — the bisulfitome — using multiple displacement amplification technology (MDA). The EpiTect Whole Bisulfitome Kit has been specially developed for the amplification of DNA after conversion with EpiTect Bisulfite Kits. It uses proven REPLI-g technology and has been adapted to the specific requirements of bisulfite converted DNA (smaller DNA fragment size and altered nucleotide composition due to bisulfite conversion), while maintaining the converted sequence representation. Typical DNA yields from the EpiTect Whole Bisulfitome Kit are 1–3 μg per reaction, sufficient for up to 300 PCR analyses from just a single EpiTect bisulfite reaction.

Performance

The EpiTect Whole Bisulfitome Kit is the ideal tool to provide sufficient DNA for all downstream methylation analyses, whenever bisulfite converted DNA is limited. This whole bisulfitome amplification (WBA) procedure provides high yields of bisulfite converted DNA with accurate locus representation, when used in conjunction with EpiTect Bisulfite Kits. The EpiTect Whole Bisulfitome Kit has outperformed amplification kits tested from other suppliers (see figures " High amplification efficiency" and " Reliable whole bisulfitome amplification").
See figures

Principle

Methylation analysis of genomic DNA sequences can be limited by the small amount of sample available. The EpiTect Whole Bisulfitome Kit provides highly uniform amplification across the entire bisulfite converted genome, with negligible sequence bias (see figure " EpiTYPER MALDI-TOF analysis of WBA DNA"). The method is based on isothermal multiple displacement amplification (MDA) technology. A uniquely processive DNA polymerase with a 3'→5' exonuclease proofreading activity maintains high fidelity during the replication process. 

The EpiTect Whole Bisulfitome Kit has been specially developed using proven REPLI-g technology and has been adapted to the special requirements of bisulfite converted DNA (smaller DNA fragment size and changed nucleotide composition due to bisulfite conversion), while maintaining the converted sequence representation. Best results are obtained when used in combination with EpiTect Plus Bisulfite Kits, which contain a uniquely formulated DNA Protect system. This enables effective DNA denaturation, which is necessary for complete cytosine conversion, and prevents the excessive DNA fragmentation usually associated with high temperature and low pH conditions of the bisulfite conversion reaction. Preventing DNA fragmentation enables subsequent amplification of large DNA fragments. Typically, DNA yields of 1–3 μg are generated per reaction using the EpiTect Whole Bisulfitome Kit.

Procedure

The convenient one-step reaction setup involves incubating bisulfite converted template DNA with a mixture of reaction buffer and REPLI-g DNA polymerase. After heat inactivation of the polymerase, the amplified DNA is ready for analysis or storage (see figure " WBA procedure").

Accessing epigenetic information is of prime importance for many areas of biological and medical research — particularly oncology, but also stem cell research and developmental biology. However, the analysis of changes in DNA methylation is challenging due to the lack of standardized methods for providing reproducible data particularly from limited sample material. With its newly introduced EpiTect products, QIAGEN makes available standardized, pre-analytical and analytical solutions, from DNA sample collection, stabilization and purification, to bisulfite conversion and real-time or end-point PCR methylation analysis or sequencing (see figure " Standardized workflows in epigenetics").

See figures

Applications

The EpiTect Whole Bisulfitome Kit is the ideal tool to provide sufficient DNA for all downstream methylation analyses, whenever bisulfite converted DNA is limited. The amplification reaction produces enough DNA for 100–300 real-time PCR assays (e.g., using EpiTect MethyLight PCR Kits) or end-point PCRs (e.g., using EpiTect MSP Kits), estimating 10 ng of amplified DNA per reaction.

FAQ

How long can DNA converted with EpiTect Bisulfite Kits be stored before use in methylation specific PCR with the EpiTect MSP Kit?

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.
