  • Roche Jr Sequencing Kit Polymerase

    While prepping enriched beads for a GS Jr run last week, I messed up the addition of the polymerase. That's what I get for trying to hurry. Anyway, to fix my mistake I just opened a second sequencing kit and used the polymerase from it. Never prep a run without back-up reagents in the freezer, right?! Well, now I have a full sequencing kit without any polymerase... Grrrr...

    Any suggestion on which polymerase, at what concentration, to use as a substitute for the one that comes in the kit? I called Roche Tech Support and DNA polI at normal concentration was suggested as a substitute, but they couldn't tell me exactly what is in their kit. Just hoping someone has experience with this and could tell me exactly what will work.

    Just ask Roche to replace the polymerase.
    You may be their only Roche Jr customer left, so what else will they do with all that polymerase?

      Yeah, I tried that already. I would need to order, and pay for, a whole new kit. They do need to move as many as possible now... Too bad the price hasn't dropped.

        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...
