IntegraGen Genomics has developed expertise with RRBS and Methyl-Seq as alternative solutions to identifying CpG sites when conducting methylation studies. This permits researchers to avoid the costs of whole methylome sequencing and leverage our ability to streamline data management and analysis.

Reduced Representation Bisulfite Sequencing (RRBS)

RRBS is an efficient and high-throughput technique used to analyze the genome-wide methylation profiles on a single nucleotide level. As a result of the high cost and depth of sequencing needed to analyze methylation status in the entire genome, RRBS is a bisulfite-based protocol that enriches CG-rich parts of the genome, thereby reducing the amount of sequencing required while capturing the majority of promoters and other relevant genomic regions.
