    size shift after PCR amplification

    Hi all,
    This is my first time making library for ChIP-seq. I was using trueseq v2 lt sample prep kit. I did the size selection after ligation and cut the gel between 250bp and 300bp. But after PCR amplification, the library size was increased to more than 350 bp . Any one has similar issue? Thanks for any advise for trouble shooting.

    Hi,

    I have exactly the same problem...did you solve it? Could you please update me?! It would be incredibly helpful! I´m really getting crazy with this ChIP library prep..
    THANKS A LOT!

      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
