    Ligating barcodes to amplicons

    Hi all,
    I am new to the forum and to next-gen in general. I am working on preparing a library of amplicons (20 different amplicons per individual sample - 96 to 180 samples) and I want to barcode the amplicons so that I can identify which individual they are from. Can barcodes/indices be directly ligated to the poly-A tail resulting from PCR or do I first need to blunt the end, apply a poly-A tail and then ligate? Thanks for your thoughts and patience!

      Yes I would alwasy make it blunt end and perform the A-tailing. You could also design fusion primers with the adapter and MID so after PCR you can start emPCR without ligating.

          Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
          by SEQadmin2



          CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

          Despite this, “CRISPR helped turn genome editing from a specialized technique into          ...

          Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
          by SEQadmin2


          Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

          The systematic characterization of the human proteome has          ...
