  • Finding circular DNAs

    I've seen a few older threads on this, but no real consensus yet. Anyone have a script or method for finding circular DNAs (*osmids, minicircles) in an assembly? I suppose it's really just as "simple" as discovering the motif which is repeated and the beginning and end of the contig where it's circularized. Anyone attempted anything like this yet?

    I looked for plasmids in my assemblies by looking for contigs with the same sequence at both ends. I was able to verify that some of the contigs were plasmids by PCR and sequencing but I was not able to get a product for most of them though I was not very exhaustive in the primers that I tried. While this method works, I don't know that I would trust that you found circular DNA without a second verification.

      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...
