  • Ribo-zero - FastQC plots - Per sequence GC content

    Dear all

    Running Ribo-zero kits on human data, seen consistent FastQC plots like this.
    Looks like a few very highly expressed ncRNAs, a result of the kit producing far more variable coverage and types of transcripts? Any comments appreciated.

    Hi Elsie, did you ever figure this out? We are seeing something very similar in some recent RNA-seq data generated using the Ribo-zero kit. We have never seen such things when we use poly A selection. We removed residual rRNA sequences (~2-6%) and that eliminated some of the weirdness, but the profile is still quite odd. David

      Even though the profile may be odd you should go ahead and analyze the data to see what it looks like. Things may be fine.

        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...
