  • TruSeq PCR Free question

    I am preparing samples using the TruSeq DNA PCR Free library kit with UDI adaptors. The PI has requested that we perform Pippin Prep post adaptor ligation to remove adaptor contamination and target a narrow size distribution. Question is... because the protocol does not include denaturation prior to the final sequencing step, the non-homologous Y-shaped adaptors results in an atypical migration pattern on agarose gel and the Bioanalyzer results are substantially larger (750bp) than would be predicted (~350bp insert +adaptor range). Should I heat denature the samples prior to putting on Pippin Prep? Thoughts?

    I don't have any advice but want to know if you tried this and if it worked out.

      The PI did not want to advert from the protocol without assurance from Illumina or Sage Science that this would work, so unfortunately, no we did not try this. Sending the samples out for sequencing today.

        Recent Advances in Sequencing Analysis Tools
        by seqadmin


        The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

        Essential Discoveries and Tools in Epitranscriptomics
        by seqadmin




        The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
