  • Poor DNA prep

    Hi. I have some samples from another lab that were prepped with the Qiagen kit. All I have is a limited amount of DNA, & the DNA is just okay quality. I did a clean up and ran them on the Miseq. Some of the sequencing quality is poor. Any recommendations for improving the data quality on the analysis side? Or even something to do if I redo the library prep? Thanks! The samples I prepped ran fine, so it isn’t a run issue.

    Could you let us know what specific problems you see with the data (and the DNA samples?)?

      What library prep tools are at your disposal? I'd suggest Nextera XT for low-concentration samples. You could also reamplify your libraries prior to normalization. If your samples are low on concentration, try vacuum concentration.

        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...
