  • Metagenomic DNA/RNA from human tissue samples

    Hi,

    Is anyone extracting microbial DNA/RNA from human (or animal) tissue? I've got some kidney biopsies that I want to look at the microbiome but I'm not having much luck in finding a protocol to isolate the nucleic acids. Any advice, kit recommendations etc would be gratefully received.

    Thanks,

    Claire

      Do you mean extraction or enrichment of microbial DNA/RNA? For extraction, we've been using the AllPrep kit from Qiagen with reasonable success.

      @nucacidhunter, how much enrichment do you see using the NEBNext? We've had pretty limited success (~20-40%), depending on sample.

      Enrichment of microbial RNA seems trickier - I haven't heard of anything besides the theoretical "you can use an array to pull out human RNA".

        I have not used them but following paper has compared NEBNext Microbiome DNA Enrichment Kit and the Molzym MolYsis Basic kit. They use different strategies for DNA enrichment.

        Metagenomic whole genome sequencing for detection of pathogens in clinical samples is an exciting new area for discovery and clinical testing. A major barrier to this approach is the overwhelming ratio of human to pathogen DNA in samples with low pathogen abundance, which is typical of most clinical …

          Strategies for Sequencing Challenging Samples
          by seqadmin


          Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
