  • Droplets, beads & wells

    Hi,

    Can anyone point me in the direction of a post or publication that lists how the droplet size for emPCR, the bead size and the well dimensions of the various Ion chips vary? Are all of the droplets formed (between chip types) at the same dimensions? If so, what size is that? The beads must change size as the wells become smaller, so perhaps that has an impact on the associated droplet size required? Certainly it would make sense that you need an awful lot more droplets emPCRing the material destined for a PII chip (660 million wells), rather than a diminutive 314. And how do these factors impact the final loading of the bead, in terms of copies of clonally amplified material attached to an individual, chip-specific bead?

    Any information would be much appreciated.

    I only have part of what you're looking for, namely, well dimensions; and unfortunately it doesn't cover the PII. However, here it is:


    Oh, edit - here's a very nice thread here in Seqanswers with beautiful SEM images of the chips:

      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 on Modified Bases...

      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...
