  • Do we need controls for NGS?

    This is a kind of silly question but hope somebody can help me out here. When people do NGS, do they need to spike in controls? Can someone maybe direct me to a few papers on this?

    Thanks a lot!

    I haven't heard of anyone spiking in controls, though perhaps in a few less common pipelines it is used. As far as I know it's not used for RNA-Seq, SNP calling, genome assembly or ChIP-Seq. The controls most people use are simply a control condition, e.g. untreated cells for RNA-Seq, wild type for SNP calling, different IgG pull-downs for ChIP-Seq (there was some discussion about these earlier). I'm not sure what you could use as a control for genome assembly, but it may or may not require one.

      Thanks a lot! I am thinking of copy number variation assays or microRNAs and just a control sequence for quantification. Does this make sense? Thanks!

        Exploring the Dynamics of the Tumor Microenvironment
        by seqadmin




        The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

        Exploring Human Diversity Through Large-Scale Omics
        by seqadmin


        In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
