    lack of blocking primer in pre and post hyb...

    Hi,
    It looks like I made a mistake in the hybridization library prep. Following the Rohland2012 protocol I forgot to use truncaded primers for pre-hyb (6 cycles). I used the fully indexed and flow cell ready primers for this step (no blocking primers added either)...
    After the post-hyb amplification I was able to see a product, but after the sequencing was completed almost exclusively illumina adapters were present. Does it look like a showcase for daisy-chaining PCR product ?
    What are my options with regards to library ? Can I simply go to post hyb library left over and use blocking primers ? Shall I go back before pre-hyb ?
    Thanks for any help!

    I would do the hyb again with the blockers.

      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
