  • Oxford Nanopore

    For originality this is the first 3rd gene sequencing by destruction. An exonuclease feeds cleaved bases into a modified hemolysin, while the potential is monitored. According to Oxford modified hemolysin (more specifically the cyclodextrin modification) interacts differently with each base resulting in a different potential drop allowing the base discrimination.

    Pros: Look ma, no label. No amplification, no label, this is a close to pure DNA readout as one can imagine (might also do methylated DNA)
    Con: Lipid bilayers are notoriously fluid causing motion in the pore. Manufacturing and kitting lipid bilayers as consumables, logistical nightmare. This is a great technology for a single pore, but pore arrays for this readout and the bilayer will be another large hurdle. Commercialization will be VERY challenging, perhaps this would be better as a service?

    I will be interested to see how they progress.

    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
