  • Testing a Rapid Library

    Does anyone have a protocol and primer sequences for testing a RL by aqueous phase PCR?

    Thanks!

    Not specifically aqueous phase, but maybe the following will be a start.

    Matthias Meyer paper in 2008 has the emPCR primer sequences. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2248761/

    forward primer 5′-CCATCTCATCCCTGCGTGTC-3′
    reverse primer 5′-CCTATCCCCTGTGTGCCTTG-3′

      I made some primers using the sequences found in the TCB (or is it an Application Note?) that describes unidirectional amplicon sequencing using the Lib-L primers. You can use the adapter sequences in there to make some primers that will amplify any library that can be sequenced with Lib-L chemistry.

      I have also used those primers to rescue libraries that had various kinds of sequencing problems by amplifying for a few cycles, then size-selecting the product. What you end up with is a sequencing library where all molecules are functional (like an amplicon library) instead of just those that ligated successfully, and that you don't need to denature before setting up emPCR. in my experience, those libraries tend to sequence better than before doing the amplification.

        Thanks, all.

        Presumably, when you reamplify your shotgun library, you're using the same cycling protocol provided in the Small Fragment Removal TCB. I don't suppose the exonuclease step is necessary if you're size selecting again anyway.

          A Brief Overview and Common Challenges in Single-cell Sequencing Analysis
          by seqadmin


          ​​​​​​The introduction of single-cell sequencing has advanced the ability to study cell-to-cell heterogeneity. Its use has improved our understanding of somatic mutations1, cell lineages2, cellular diversity and regulation3, and development in multicellular organisms4. Single-cell sequencing encompasses hundreds of techniques with different approaches to studying the genomes, transcriptomes, epigenomes, and other omics of individual cells. The analysis of single-cell sequencing data i...

          Introduction to Single-Cell Sequencing
          by seqadmin
          Single-cell sequencing is a technique used to investigate the genome, transcriptome, epigenome, and other omics of individual cells using high-throughput sequencing. This technology has provided many scientific breakthroughs and continues to be applied across many fields, including microbiology, oncology, immunology, neurobiology, precision medicine, and stem cell research.

          The advancement of single-cell sequencing began in 2009 when Tang et al. investigated the single-cell transcriptomes
