SAN FRANCISCO (GenomeWeb) – Boreal Genomics has developed a sequencing technique that it said can improve the detection of low-frequency mutations in cell-free DNA assays, while keeping sequencing costs down.

The firm, which described the technique recently in a paper posted to the BioRxiv preprint server, said that it could be complementary to previous technology it has developed, OnTarget, which targets known activating mutations in cancer genes.
