  • Synteny analysis of unfinished sequencing species

    Dear everyone,

    Are complete genomic sequences or chromosome sequences necessary for synteny analysis ?
    If i just have some scaffold sequences of a species, Can i use it to analyze synteny of a targeted gene?

    Thank you very much!

    It depends on what your questions is. For looking a patterns of micro-synteny, you only need to compare small regions, and it isn't necessary to have whole chromosomes. However, it doesn't make sense to analyze synteny for a single gene because you need at least a few genes in a scaffold to possibly infer some type of rearrangement.

      If you have other ways to order the genes, such as a linkage or physical map, then you would be able to look for chromosome-scale rearrangements. But as SES says, you'll need some large scaffolds otherwise and then only be able to see changes if there are so many that every small region of the genome is altered.

          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...
