    No, that's the original image that is also inaccurate for a different reason - see original post. It seems that the Illumina folks did not have anyone who understands the technology check the diagrams coming out of their illustration department/provider. I wanted to use an original Illumina illustration in a talk that describes the principle of bridge amplification but the official diagrams will confuse the audience, so I think I'll create my own.
    Try the original paper: Nucl. Acids Res. (2000) 28 (20): e87. doi: 10.1093/nar/28.20.e87. Figure 1.

    Is this illustration better: http://www.illumina.com/documents/pr...sequencing.pdf

    This Illumina figure is also incorrect. As per my understanding, it is not possible to generate double stranded molecules with free ends!

    Yeah, that seems a little misleading. I would say that panel b more accurately represents the state after the initial cycle of amplification (primer extension). The flow cell bound primer has been extended using the hybridized library molecule template, then the original template strand has been denatured and washed away.

    It seems the description of the initial stages in the this thread aren't quite accurate.

    Are the Illumina diagrams correct?

    Is it true that single-stranded DNA libraries are initially BOUND directly to the flow cell as suggested in Illumina's diagrams (see panel b in attached figure). I always assumed they simply hybridized to the primer lawns.

    Multiomics Techniques Advancing Disease Research
    by seqadmin


    New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”

    A major leap in the field has
