    Issue with Agilent 2100 BioAnalyzer HS DNA Assay Trace

    Hi everyone,

    I have been prepping libraries for low biomass samples and got these results from my most recent chip. DNA was extracted from oral and nasal swabs, and library prep was performed with a NEB Next Ultra II FS DNA library prep kit. Does anyone have an idea on why my 3rd sample is inching up on the Y-axis? I'm aiming for peaks around 300bp, which can be seen in the other samples run here. The problematic trace comes from an oral swab.

    Thanks for your help,
    Beatrice

      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      ...

      New Genomics Technologies Take Aim at Long-Standing Limits
      by SEQadmin2


      Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

      We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing      ...
