  • Sequencing problems of bacterial strains wihch produce a lot of EPS

    Hi,

    I extracted the DNA by Chloroform extraction and had also a very high yield. But unfortunately as I started sequencing with the PacBio platform I had a veryy low number of reads. I assume that some organic molecules interfere with the polymerase. My bacterial strain is a strong EPS Producer and this is maybe the cause for the low read numbers.

    Does anybody have any experience whith such Problems? Or can recommend me a protocol where I certainly get rid of all the EPS?

    Thanks a lot...

    On PacBio's Sample Net, there is a shared protocol for using magnetic beads to remove contaminants. http://www.smrtcommunity.com/Share/P...eName=Protocol

    I also advise contacting the local PacBio field applications scientist (yes, there is one in Switzerland). He may have some other tips on how to remove specific contaminants depending on the extraction and/or cleanup protocol you used.

      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...
