    Ion Torrent Metagenomics flows

    Hello all, I've been looking for optimalization of my metagenomics sequencing process.
    I usually use 316chip on PGM and as default in IonTorrent 16S metagenomics workflow inumber of flows is setted to 850. It results with half of volume of every dNTP left in bottles and I'm afraid of runnning next sequencing without replacement them to new. It is really increasing my sequencing cost because I need to use new inicialization chemistry for each sequencing. I use about 400 bp length fragments but in real its average is about 250 bp(as I can see in the end sequencing summary). Can I decrease number of flows to maybe about 650 to reach two sequencing processes with one inicialization?

    2x 650 is maximum you can get away with.

    With 650 flows, estimate is that mean read length is 346, and 90% of reads should make it to 325.

      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
