Smart-RRBS for single cell methylome and transcriptome analysis [scRRBS]

ABSTRACT: The integration of DNA methylation and transcriptional state within single cells is of broad interest. Several single-cell dual- and multi-omics approaches have been reported recently that will enable further investigation into cellular heterogeneity including the discovery and in depth study of rare cell populations. Such analyses will continue to provide important mechanistic insights into the regulatory consequences of epigenetic modifications. Last year we reported a new method for profiling the DNA methylome and transcriptome from the same single cell. Here we present details of the protocol and provide guidance on its utility. Our Smart-RRBS protocol entails physically separating mRNA and genomic DNA and combines Smart-Seq2 and Reduced Representation Bisulfite Sequencing (RRBS). It generates paired epigenetic promoter and RNA-expression measurements for a substantial fraction (approximately one-fourth) of protein-coding genes in a typical single cell. It also works for micro-dissected tissue samples comprising hundreds of cells. The protocol, excluding sequencing, takes ~3 days to process up to 192 samples manually
