N2 - Chromosome-derived extrachromosomal circular DNA elements (eccDNAs) are detected in all eukaryotes examined so far. Here I describe the Circle-Seq protocol, applicable for physical enrichment of eccDNAs of a broad size range, combined with sequence confirmation of circular structures.Briefly, by concise alkaline treatment and gentle gravity flow-through an ion-exchange column, eccDNAs are enriched in the eluate fraction. EccDNAs are enzymatically isolated by extensive Plasmid-Safe DNase digestion of linear chromosomes and further enriched by φ29 rolling circle amplification. By means of high throughput sequencing of amplified eccDNA and custom eccDNA mapping software, around ten-thousand unique eccDNA types could be detected at nucleotide resolution in a million human muscle nuclei by this method.
