    PubMed: Molecular diagnostics for personal medicine using a nanopore.

    Molecular diagnostics for personal medicine using a nanopore.

    Wiley Interdiscip Rev Nanomed Nanobiotechnol. 2010 Apr 20;2(4):367-381

    Authors: Mirsaidov UM, Wang D, Timp W, Timp G

    Semiconductor nanotechnology has created the ultimate analytical tool: a nanopore with single molecule sensitivity. This tool offers the intriguing possibility of high-throughput, low cost sequencing of DNA with the absolute minimum of material and preprocessing. The exquisite single molecule sensitivity obviates the need for costly and error-prone procedures like polymerase chain reaction amplification. Instead, nanopore sequencing relies on the electric signal that develops when a DNA molecule translocates through a pore in a membrane. If each base pair has a characteristic electrical signature, then ostensibly a pore could be used to analyze the sequence by reporting all of the signatures in a single read without resorting to multiple DNA copies. The potential for a long read length combined with high translocation velocity should make resequencing inexpensive and allow for haplotyping and methylation profiling in a chromosome.

    16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
    by SEQadmin2




    NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
