Researchers used the TruSeq Custom Amplicon Kit on the MiSeq System to identify rare mosaic mutations that lead to neural malformations. This study determined that NGS is a better alternative than Sanger sequencing for detecting somatic mutations.
This dual-indexing method uses the MiSeq System to sequence DNA barcode markers. The approach reduces both per specimen costs and labor time by nearly 80%, compared to Sanger sequencing. It also allows recovery of multiple sequences per specimen, for deeper analysis of genetic variation in target gene regions.
Researchers use next-generation sequencing (NGS) on the MiSeq System to screen for HIV-1 genotypic resistance to antiretroviral therapy. NGS demonstrates a higher sensitivity than Sanger sequencing for detecting minority variants involved in resistance.
