    low dna concentration of IP samples

    Hi everyone. I am doing preparation of chip-seq sample. After IP and reverse-cross linking, I purified DNA using qiagen columns. But Nanodrop showed 30ng/μl of non-IP control samples, while IP samples showed only 10ng/μl. Furthermore, 260/230 ratio of IP samles was very low, only 0.5.
    (260/230 ration of control samples showed normal value, 2.0)
    Shoud I proceed to validation using bioanalyzer?

    Best regards.

      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      ...
