  • MinIon Prep Kit Selection (Ligation vs. Rapid)

    Hey all,

    I'm looking to sequence a handful of pure bacterial isolates for WGS and de novo assembly. Our group has decided to go with a combined Illumina/Oxford nanopore approach. While our Illumina protocols are well developed (MiSeq v3 using the Pulsenet protocol), our MinIon sequencing is something we're having to start (more or less) from the ground up. This would be an ongoing project sequencing around 2-12 isolates a month.

    Does anyone have insight into which kits have worked best for them? A lot of the literature I see discusses using the Rapid Sequencing Kit (SQK-RAD004), but not much in the way of the Ligation Sequencing Kit (SQK-LSK109). For my purposes, will the Rapid sequencing kit (in combination with Illumina sequencing) be enough? Is the Ligation kit + Illumina effectively overkill? I don't want to suggest a kit that requires $1500 of reagents just for a $600 kit to get essentially the same results.

    Thanks!

      In our lab, we had trouble getting long DNA from the extractions and so the rapid kit didn't work for us. It has a built in fragmentation step that also applies the adapters/barcodes. The ligation kit you don't have to fragment the DNA to attach the adapters or barcodes so that's what we have been using.

      If you're getting high molecular weight good quality DNA from your extractions it's my understanding that there's no reason that the rapid kit wouldn't work for you.

        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...
