Multiplexed ctDNA fragments (~150bp) mixed with nucleosomally fragmented wildtype cfDNA background in human plasma. The cell-derived ctDNA fragments are generated by Anchor’s unique multiplexed gene-editing method and are nucleosomally fragmented to around 150bp. The cell-derived variants are suitable for both the amplicon-based and capture-based methods. The synthetic ctDNA fragments are…

Sequencing data for a single human genome, at 30× coverage, takes up to 70 gigabytes of storage. Illumina instruments produced 280 million gigabytes of data in 2021 alone, and by 2025, we’ll need storage capacity for 40 billion gigabytes—and that’s just for human genomes.

RNAs have attracted much attention in forensic body fluid/tissue identification (BFID) due to their tissue-specific expression characteristics. Among RNAs, long RNAs (e.g., mRNA) have a higher probability of containing more polymorphic sites that can be used to assign the specific donor of the body fluid/tissue. However, few studies have characterized…

Allele design and guide selection For multi-exon genes, a critical region (one or more exons) was identified as shared among all annotated full-length transcripts whose removal was predicted to result in a frame-shift mutation and introduction of premature stop codon greater than 50-nt from the final splice junction increasing the…

By MaryAnn Labant Back in 2016, a group of researchers led by Harvard’s David Liu, PhD, published a paper in Nature that reported the development of base editing. Base editing, they wrote, is “a new approach to genome editing that enables the direct, irreversible conversion of one target DNA base…

Data production Complete Y chromosomes from six different human haplogroups were isolated as previously described17 (Fig. 1a, b). In brief, chromosomes were obtained from lymphoblastoid cell lines (LCLs) used in the 1000 Genomes Project31 (1kgp) and sequenced on the ONT MinION. We also made use of the Y chromosome sorted ONT…
