  • Resuspension Buffer (RSB) added to RNA samples in Truseq mRNA Protocol

    Hello ,

    can Resuspension buffer prevent mRNA from binding to RNA beads in first step of Truseq protocols?
    it was used instead of water to bring volumes of samples to 50uL

    if any one can provide the contents of the buffer too ?

    thanks alot in advance,

    GM

    Hi,

    I'm not too sure about the resuspension buffer preventing the binding to the RNA beads, but in any TruSeq protocol I've used the buffer was used to remove the libraries from the beads after binding and washing so it could possibly inhibit binding but someone else will have to confirm that.

    In a previous position we had a homemade RSB recipe which was just TE buffer + Tween-20 (I can't remember off the top of my head but it might have just been 1% Tween-20) and it worked fine. I don't know the actual chemical make-up though, sorry.

      Thank you for your reply
      Yes it has multiple use to release templates off the beads after thermalcycling episodes
      So that is what hit me to ask is it by composition unbind tue teplates or the heat is the starter

      Thanks alot again

        thank you for sharing your notes, I have completed the prep the RSB did not affect the binding specially after thermal cycling step which might enhance the binding of the poly-A to the T-tail of the beads.

          Hi GenomeM,

          Thanks for giving an update on this, it's good to know that the RSB didn't affect the binding! I'll keep that in mind for the future.

          Cheers.

            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...
