    RNA Extraction from Frozen EDTA Blood

    Is there anyone who can isolate RNA from frozen EDTA blood sample or develop a method? I am open to all kits and methods on this subject.

    It has been several years since I've had to do this, but I remember using the QIAamp DNA Blood Kits and it worked fine. I also had a colleague use another kit from Thermo that worked well but I don't remember the name.

      What you say is correct. QIAamp DNA Blood works on frozen blood. But I need it for RNA. I always came across a warning in QIAgen kits such as "Frozen blood samples are not recommended for RNA." The Nucleospin RNA kit will arrive within 1 week. I will try that kit for my optimization work.
      If this kit does not work, I will try changing a few methods or combining the steps of some protocols. By adding things like that water bath, aluminum, heat block etc.

        Hi Mehmet, did you get any good results so far? I have been trying to work with frozen EDTA samples in the last weeks and am now planning to do single nucleus sequencing, hoping are chances to get relatively high RNA yield. I have also tried aluminum thawing and found this publication for improved quality: https://www.nature.com/articles/s415...Rec=false#Sec9.

          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
