  • Better to risk low concentration library or further amplification?

    Here's an issue which has arisen with some SureSelect processed libraries for the Illumina: after the hybridization the amount of library is barely within spec -- hence my question about quantitation.

    So, the question is which path to take: push the libraries forward as is, with a risk of missing peak sequencer yield due to suboptimal cluster density, or run a few more (how many?) cycles of PCR to increase the concentration but also up the odds of getting PCR duplicates?

    It worked fine for me and I could barely detect it on my Nanodrop. We are in the process of evaluating the Kapa Q-PCR kit which I think the Broad Institute has switched to.

      Check out this thread.
      You can prep a flowcell with a library that is <100pM with no problems.

        No, I think the expected PCR duplicate rate is irrelevant to the PCR cycles. The duplicate rate is determined by the number of molecules before amplification.

          Exploring the Dynamics of the Tumor Microenvironment
          by seqadmin




          The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

          Exploring Human Diversity Through Large-Scale Omics
          by seqadmin


          In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
