From: Non-random fragmentation patterns in circulating cell-free DNA reflect epigenetic regulation
Fragment length distributions. For both cfDNA samples, the average fragment length was at 165 b.p., which corresponds to a single nucleosome. The dinucleosomal peak with average fragment length of 308 b.p. is also notable for both cfDNA samples. Panel B demonstrates zoom of panel A, representing only minor fraction of fragments. Red arrows note periodicity below major distribution peak.
