  • Why are the ends different in RNA seq?

    Hi guys,
    I have a feeling that everyone but me knows or has figured this out...

    Why are the ends different in a RNA seq library? I can see that the both primers anneal in the 3' end to the adaptor sequence and that the genomic sequencing primer only anneal to the long PCR primer, but I can't figure out what prevents the final library to be a random selection of fragments with primer 1.1 or 2.1 in both ends and some with different ends. What am I missing?

    Happy sequencing,

      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
