  • sequencing microsatellites

    Dear all,

    I was wondering if any of you have information on sequencing microsatellite repeats (amplicons) on a 454 platform.

    Essentially, I would like to get some information on the accuracy when sequencing microsatellite amplicons. Do you get the two alleles (e.g. heterozygotes) in equal proportions or do you get a distribution of several repeat lengths due to pcr-errors? If so, what kind of coverage (50x, 100x) do you need to estimate the "correct" alleles?
    And is there any difference between di-, tri, tetra or penta-repeats as you would expect?

    I would be gratefull if any of you could point me to some papers on this topic or share your experience.
    Thanks!

    Note: I do not ask for info on how to use 454 seq to develop new microsats. There are plenty of papers on that.

    Hi Koen,

    I am wondering the same thing. Please if you have any information of some labs that have already tried this methodology please let me know. In our lab we are thinking of a pilot project using Illumina for amplicon sequencing. But I would like to know if there is some body that have tryied and pros and cons of the technique, actually for me is strange that no-body has published about this issue.

    Thanks for you post and looking forward for any help

      The Impact of AI in Genomic Medicine
      by seqadmin



      Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

      Multiomics Techniques Advancing Disease Research
      by seqadmin


      New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”

      A major leap in the field has
