  • RNA-Seq: High-Throughput Illumina Strand-Specific RNA Sequencing Library Preparation.

    Syndicated from PubMed RSS Feeds

    High-Throughput Illumina Strand-Specific RNA Sequencing Library Preparation.

    Cold Spring Harb Protoc. 2011;2011(8)

    Authors: Zhong S, Joung JG, Zheng Y, Chen YR, Liu B, Shao Y, Xiang JZ, Fei Z, Giovannoni JJ

    INTRODUCTION Conventional Illumina RNA-Seq does not have the resolution to decode the complex eukaryote transcriptome due to the lack of RNA polarity information. Strand-specific RNA sequencing (ssRNA-Seq) can overcome these limitations and as such is better suited for genome annotation, de novo transcriptome assembly, and accurate digital gene expression analysis. This protocol describes a simple and robust method to generate ssRNA-Seq libraries for the Illumina sequencing platform. It has significantly increased the throughput to 96 libraries in a two-day preparation while simultaneously lowering the reagent costs to below ten dollars per library. It is compatible with both single-read and paired-end multiplex sequencing and, most importantly, its data can also be used with existing conventional RNA-Seq data. This is a significant advantage, because it enables researchers to switch to ssRNA-Seq even if a large amount of data has already been generated by the nonstrand specific methods.

    I run through the CSH strand-specific RNA sequencing protocol. There is a purification step using RNAcleanXP after the first strand synthesis. But then only use the purified first strand product, buffer, dNTPs, RNase and DNA polymerase I for second-strand synthesis. I wounder if any primers needed?

      The Impact of AI in Genomic Medicine
      by seqadmin



      Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

      Multiomics Techniques Advancing Disease Research
      by seqadmin


      New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”
