  • Can I use default sequencing primers for Miseq?

    I use below PCR primers to prepare libraries for Miseq amplicon sequencing:

    i7-INDEX2-Spacer- gene_specific_Primer

    CAAGCAGAAGACGGCATACGAGAT TCGCCTTA GTCTCGTGGGCTCGG +gene_specific_Primer

    i5-INDEX2-Spacer+gene_specific_Primer
    AATGATACGGCGACCACCGAGATCTACAC-CTCTCTAT-TCGTCGGCAGCGTC+gene_specific_Primer

    Compared to Nextera adapters, my primers do not include the tagmentation sequence. I tried to look up Miseq sequencing primers, but still not sure whether my adapters are compatible with Miseq sequencing primers.

    Can I use default sequencing primers in Miseq cartridge for sequencing? Does anybody know any website or document to verify that?

    My guess is that you cannot use the "default" sequencing primers with your scheme.

    You appear to have directly attached your gene-specific primer sequence directly to the i5 and i7 illumina indexing primers and therefore lack the sequencing primer binding site, which is actually contained within the Nextera transposase sequence.

    Pages 3 and 4 of the following Illumina document might help you:

      Thanks a lot for your reply.
      Are there any document/post(s) mention that "the sequencing primer binding site is actually contained within the Nextera transposase sequence"?

        You are right!

          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...
