    MiSeq run failed; low clustering, but good QC

    Have a strange situation, our latest MiSeq run failed for 16S - from a protocol (EMP @ ArgonneNatLabs) that we use all the time.

    The clustering was unusually low (180 vs the expected 800) and we did a KAPA just prior to dilutions (those are correct, I checked). The run QC, Clusters %PF and all the obvious look very good - when the run finished, it did not demultiplex and says "failed".

    I've contacted Illumina, but this being a Saturday, I thought I'd see if anyone has seen this before?

      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
