  • Dual-index vs single index

    What would be the benefit from using 2 x 8bp dual indexes vs say... 1 x 16bp single index for a paired end read?

    One good reason is to identify barcode swapping between samples that can happen during PCR:

      How many adapters or primers would you need for each of those scenarios to identify a given number of samples?

        Thanks, this makes sense. According to the paper, it looks like contamination is also an issue, if you pool after PCR.

          I think SNPsaurus's point is more important, however. You can get by with far fewer distinct adapters by using the combinatorial aspects of a two-index system.

            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...
