The authors present a protocol, isoCirc, for the full-length sequence determination of circular RNAs. The method features rolling circle amplification followed by nanopore sequencing, and includes a description of an integrated computation pipeline. A catalogue of over 100,000 circular RNAs across 12 human tissues and the HEK293 cell line was produced, including ~40,000 isoforms.
BluePippin was used to size select the RCA products after debranching prior to ONT MinION library prep.
