Product Name:  Post-Bisulfite DNA Library Preparation Kit (For Illumina)
Description:  The kit is a complete set of optimized reagents to prepare a DNA library - after successful bisulfite conversion - for various Illumina® platform-based bisulfite sequencing (bisulfite-seq) assays, such as whole genome bisulfite sequencing (WGBS), oxidative bisulfite sequencing (oxBs-seq), reduced representative bisulfite sequencing (RRBS), and other bisulfite-based next generation sequencing applications. The optimized protocol and components of the kit allow both non-barcoded (singleplexed) and barcoded (multiplexed) DNA libraries to be quickly constructed using sub-nanogram input concentrations of DNA since the DNA is first bisulfite-converted and then used for library preparation.
Background:  Several methods, including whole genome bisulfite sequencing (WGBS) and reduced representation bisulfite sequencing (RRBS), are currently used for genome-wide DNA methlyation analysis. These methods convert unmethylated cytosines to uracil while 5-methylcytosines remain unchanged by the bisulfite treatment. This allows epigenetic differences to become genetic differences, which can be subsequently detected via sequencing at the single-based resolution level and on a genome-wide scale. However, practical use with such current methods are not ideal as they (1) need large amounts of DNA (>1 µg) as input material, which is difficult to prepare from limited biological samples such as tumor biopsy, early embyros, embyronic tissues, and circulating DNA; (2) require DNA to first be sheared and then ligated to adapters, followed by bisulfite conversion (post-ligation bisulfite conversion), which causes substantial amounts of DNA fragments contained in the adapter-DNA fragment constructs to be broken and thereby forms mono-tagged templates that become removed during library enrichment; and (3) are time-consuming (2 days). The Post-Bisulfite DNA Library Preparation Kit (For Illumina®) is designed to overcome these weaknesses.
