They love it!
The new Diagenode Premium RRBS Kit makes it easy to use RRBS cost-effectively and with high throughput, using early sample pooling and multiplex sequencing. Most importantly, the method provides an improved coverage of up to 4 million CpGs for the human genome. We successfully used this protocol on more than 1,000 samples comprising of six different species, various cancers, FFPE and lowinput samples.

Accurate determination of DNA methylation level
Excellent results were obtained using Diagenode’s Premium RRBS kit: almost 90% alignment rate, 4.1 million CpGs covered and bisulfite conversion rates around 99.5% for all samples. DNA methylation percentages in the region of IGF2 obtained with the Diagenode’s Premium RRBS Kit. Two human cell lines were analyzed: Gm12878 and MCF7. The MCF7 cell line was studied in duplicates. Each peak represents the DNA methylation percentage at one CpG. The methylated CpGs are shown in red and the unmethylated CpGs in grey.
How it works
By cutting the genome using the restriction enzyme MspI (CCGG target sites) followed by size selection, DNA is enriched to represent CpG-rich genomic regions (including CpG islands, CpG island shores, enhancers, and other gene-regulatory elements), which are particularly relevant for epigenetic regulation. Similar to exome-sequencing for mutation discovery, the RRBS protocol enriches for some of the most interesting target regions and thereby achieves a reduction in sequencing cost of a factor of 10-20 compared to whole genome bisulfite sequencing.
