  • Low throughput DNA quantitation?

    I need 200ng and 50ng/ul DNA for my downstream application. I only need to process eight samples a day. What DNA quantitation method should I use?

    Is Qubit fluorometer good enough for me???

    Both Illumina and ABI recommend Qubit over NanoDrop for quantifying DNA.

      I heartily recommend Qubit as well.
      Has anyone seen this recent piece concerning plastic leaching and DNA quantitation:

      The nice thing about the Qubit is it doesn't see anything but dsDNA, unlike the nanodrop.

        The Qubit is good, the readings are slightly higher than using a bioanalyser but the results are repeatable and much closer to reality than a nanodrop.

        The nanodrop is only useful for reading circularised DNA for SOlid long mate pair but it's still not great for this.

          The libraries I made using NanoDrop values were all very good. We bought the Qubit since it's recommended but haven't made libraries using it's values yet.

            Also, at least for protein quantification you can't use common protein buffers to dissolve your proteins in on the Qubit. You have to use their proprietary buffer and they won't even tell you what's in it.

              Nice. Thank you all for your replies. I think I will go with Qubit then.

                Current Approaches to Protein Sequencing
                by seqadmin


                Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

                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...
