NGI Uppsala (SNP&SEQ Technology) platform has developed a novel approach for quick and cost effective whole genome bisulphite sequencing (WGBS) library preparation. Compared with currently used commercial methods, this method called SPLinted Adaptor Tagging (SPLAT) has the major advantage of uniform coverage of the genome. SPLAT is based on initial bisulphite treatment of the DNA, followed by adaptor tagging of single stranded DNA fragments, and enables WGBS using low quantities of the DNA samples. The article presents validation of SPLAT against three commonly used WGBS library preparation techniques, two of which are based on bisulphite treatment prior to adaptor tagging and one is a conventional WGBS method.
The article presenting this method, including a detailed laboratory protocol, was published online in Nucleic Acids Research on November 28, 2016.
