    The bubbles were not there in the images from the two flowcells I looked at. I will check with the lab folks here to see if they have anything to add.
    Could you see what was causing the high error rates in the tiles you looked at?

      Not always. Very intermittent, but it does exist. And I can find those tiles and see the dark bubbles circles as Phillip showed. I'd go find some right now but we dump thumbnails after the run and I don't have anything running right now. I will say I haven't seen it in any of the rapid runs we've done so far.

        My instrument is a HiSeq2500 (upgraded from a HiSeq2000). What instruments do you guys have?

            Both HiSeq 2000 and 2500.

              Illumina tech support just mentioned that there is some bubble-related issue with "swath and tile drop out" at some HiSeq 2500 sites. They have launched an internal investigation.

                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...
