    high percetage of intergenic reads from RNA-SEQ

    We just finished analysis on a RNA-SEQ project, however, we found the exonic reads accounts for only 15% of total reads while intergentic reads almost reached 70%. Very confused. Any thoughts here?

    Maybe the sample is contaminated by the genome DNA ?

      We have seen a similar thing with one set of libraries and it was confirmed as carryover DNA contamination.

        I suspected DNA contamination too and thank you for confirming the case!

          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
